7 Best Headless CMS Software I Recommend for 2026

I evaluated 20+ tools to find the seven best headless CMS software. These are
Sanity, Storyblok, Hygraph, Contentstack, Prismic, Umbraco, and Prepr CMS.

Look, I’m no web developer. I don’t mess with code or follow the latest JavaScript frameworks. But as a marketer with years of experience, I know the pain of juggling content across multiple online platforms. Whether it’s updating website banners, refreshing app content, or aligning everything with an email campaign, the process can feel like trying to rewrite a billboard while driving past it at full speed.

Working with traditional CMS platforms made some tasks easier, like managing content in one place, but they often created more challenges in the long run. Their rigid templates and limited flexibility left me stuck waiting on developers for updates—or worse, unable to deliver the experiences we needed at all.

That’s when I decided to explore the best headless CMS software—and I haven’t looked back since. Headless CMS has completely changed the way I approach content. It gives developers the freedom to build exactly what we need while letting me focus on getting the right message out to the right audience, without all the back-and-forth.

Over the years, I’ve worked with a number of headless CMS platforms, each with its own strengths. These tools have made it so much easier for me to manage content, work alongside developers, and keep everything running smoothly across multiple platforms.

In this article, I’ll share with you the 7 best headless CMS platforms that I’ve come to rely on—and that my developers love too. I’ll break down their strengths, weaknesses, and what sets them apart, so you can find the one that works best for your needs.

7 best headless CMS for 2026: my top picks

These headless CMS software are top-rated in their category, according to G2 Summer Grid Report 2026. I’ve also added their monthly pricing to make comparisons easier for you.

Whether you’re a marketer or a developer looking for a flexible solution, or me, these platforms strike the perfect balance between creativity and functionality. 

As headless CMS offers key features like GraphQL API, content template builder, and governance and audit services, it is evolving the decision-making process as evident in the current headless CMS market share, projected to grow up to $22.28 billion by 2034, with a CAGR of 21.42%, as reported recently. 

7 best headless CMS systems I recommend

For me, a headless CMS is more than just a fancy buzzword. It’s the tool that gave me the freedom to manage content the way I’ve always wanted. Unlike traditional CMS platforms, which tie the backend (where you manage content) to the front end (how it looks on your website or app), a headless CMS separates the two entirely.

This separation matters because it allows me to create and organize content independently of how it’s displayed. I no longer need to wait for developers to build or refresh pages for every update. Instead, I can manage everything in one place and instantly push updates to multiple platforms. For instance, when I update a product description, it reflects across the website, app, and even our marketing materials, saving time and effort.

Meanwhile, my developers have full flexibility and control over the code they use. They aren’t tied to specific frameworks or languages and can work with modern tools like React or Vue to build dynamic, custom experiences. With APIs connecting everything together, they stay in full control of the code, and I stay in control of the content.

This balance is what makes a headless CMS so powerful. Developers build the systems; I create the pages; and together, we deliver what we need—quickly and efficiently, without compromise.

One interesting observation I noticed in G2 data was that content management was one of the fastest-growing markets, quarter over quarter, with an increase of 2.2% as per G2's state of software report last year. 

The earlier reliance of web developers or coders has now seen a shift to a smarter and more innovative medium of website creation. 

What makes the best headless CMS: My criteria

Selecting the right headless CMS wasn’t just about ticking off a list of basic features. I needed a platform that could truly bridge the gap between what marketers like me need and what developers expect to work with. To make sure I found the best fit, I focused on these key factors during my testing and evaluation:

• Ease of use for marketers: First, I wanted a CMS that doesn’t require me to call a developer every time I need to update a page or tweak some content. I need a clean user interface for managing content. I tested features like drag-and-drop editing, content scheduling, and version control. If I couldn’t navigate it quickly or train my team on it, it didn’t make the cut.
• API performance and flexibility: For my developer team, robust application programming interface (API) functionality was non-negotiable. The CMS needed to have fast, well-documented APIs (like REST or GraphQL) that allowed developers to fetch and deliver content seamlessly across platforms. We tested API response times and how well the CMS handled large datasets. If an API felt clunky or lacked flexibility, it was out.
• Omnichannel content delivery: A great headless CMS should make it easy to distribute content across multiple platforms—websites, mobile apps, IoT devices, and more. I tested how efficiently the CMS could deliver content through APIs to different endpoints and whether I could maintain a consistent brand experience across channels without extra effort.
• Scalability: Scalability is crucial, especially for teams managing large content libraries or preparing for growth. I tested how well each CMS handled increased traffic and content volume. Features like CDN (Content Delivery Network) integrations, global content distribution, and caching mechanisms were a big plus for ensuring fast load times.
• Developer flexibility: I evaluated how easily developers could integrate the CMS with modern frameworks like React, Vue, or Next.js. A platform that supported their preferred tools and workflows scored higher. I also checked for extensibility—could developers add custom plugins or extend the CMS functionality if needed?
• Content modeling capabilities: As a marketer, I need the freedom to structure content in a way that fits our strategy. I tested each CMS’s ability to create flexible, reusable content models—think modular blocks that I could repurpose across multiple pages or platforms. If the CMS restricted how I could structure or organize content, it didn’t make the list. I also looked for a previewing feature, the ability to instantly publish, and, most importantly, language translation capability for localizations. 
• Collaboration features: Since marketing and development teams work closely, I looked for features that encouraged collaboration, like user roles, permissions, and workflows. The ability to assign tasks, leave comments, and track approvals streamlined the process for both teams.
• Pricing and value for money: Let’s be real: budget matters. I analyzed each CMS’s pricing structure and compared it to the features offered. Some platforms charge extra for things like API usage or scaling content, so I had to factor in the long-term costs. A platform that delivered excellent functionality without hidden fees stood out.
• Security: Security was another critical factor. I evaluated features like two-factor authentication (2FA), role-based access control, and data encryption. The CMS also had to comply with major security standards like GDPR or SOC 2 to ensure the protection of our data and content.
• Community and support: Finally, I looked at the developer and user communities surrounding each CMS. Platforms with active forums, responsive customer support, and detailed documentation scored higher because they made it easier to solve problems quickly.

After evaluating 20+ tools, I narrowed my list down to the seven best headless CMS systems. Each of these tools offers unique strengths, from seamless content management workflows to robust developer-friendly APIs, and they’ve been tested to ensure they meet the demands of real-world projects.

The list below contains genuine user reviews from the Headless CMS Software Category. To be included in this category, a solution must:

• Offer content modeling.
• Allow for the creation, reading, updating, and deleting of content.
• Facilitate content production workflow.
• Organize content in a cloud-based repository.
• Give businesses the opportunity to repurpose content across multiple channels

1. Sanity: Best for real-time collaboration and content customization

Sanity is one of the most flexible and practical headless CMS platforms I’ve worked with. As a marketer, what stands out to me is its structured content approach. 

Apart from the standard features of creating reusable content blocks and integrations with API, I absolutely enjoyed working with Sanity Studio because of the flexibility it provides in terms of personalizing all of our workflows and processes. I can customize my dashboard to other languages apart from English. How cool is that? 

Our blog automatically refreshes with top content in real-time with Sanity instead of one of our editors manually configuring it every time. Nice, right? 

From a developer’s perspective, Sanity gets high marks for its schema customization and API performance. My developer team appreciates how easily they can define content models that work for our specific needs by writing their code from scratch or by using the already available templates in different frameworks, plugins, schemas, and snippets

These templates provide a solid starting point for common use cases like blogs, e-commerce sites, and portfolios, in my view. Our developer could even create a content block for adding real-time photomap for location data on our site. Also, its REST and GraphQL APIs are quick and well-documented and make fetching content straightforward.

One feature I’ve personally found useful is the real-time collaboration. Working with developers and content creators often involves a lot of back-and-forth, but with Sanity, we can make edits simultaneously and see updates live. This makes it much easier to finalize content without endless review cycles or miscommunication.

On the pricing side, I think Sanity offers great value, especially for teams just starting out. The free tier includes features like unlimited admin users, projects, and real-time collaboration, which many platforms lock behind paid plans. For larger teams or those handling high volumes of content, the paid plans provide more advanced features and support, but the price might seem a little costly, in my opinion.

Sanity is a powerful, flexible platform, but it does come with a learning curve, especially if you're new to schema-based systems. From my own evaluation and the sentiment in G2 reviews, more advanced workflows can feel complex for non-technical users at first. That said, the documentation is genuinely thorough and has improved noticeably of late, reviewers point to newer AI-ready resources and fuller guides that make onboarding a project today meaningfully faster than it once was.

Sanity also uses its own query language, GROQ, which G2 feedback describes as efficient but niche. In my experience, our developer team had mixed opinions; some appreciated its capabilities, while others preferred the familiarity of GraphQL. It is evident from G2 review patterns, and we even found that adopting Sanity requires some upfront investment in learning, but once you're up to speed, it delivers solid customization and control.

Regardless of these challenges, Sanity is a platform I genuinely enjoy working with. If you’re a content-heavy organization, like an e-commerce brand, media or news company, or digital agency, managing content across multiple platforms with quick updates, I'd definitely recommend giving Sanity a try for its sheer flexibility and collaborative capabilities. 

What I dislike about Sanity:

• While the documentation is fine, it can be hard to navigate for more advanced tasks, and you sometimes land on what you need only after some trial and error.
• GROQ, Sanity's query language, is an adjustment for developers used to GraphQL — but it's genuinely powerful, and once my team got comfortable, they came to value the precision and control it gives them.
  

What G2 users dislike about Sanity: 

"The learning curve at the beginning was steeper than I expected - not because Sanity is poorly designed, but because the documentation for more advanced use cases was pretty thin when I first got started. I ended up spending a fair amount of time piecing things together from community posts and examples."

- Sanity review, Samet D.

2. Storyblok: Best for visual editing and market-friendly UI

Storyblok has been an interesting experience for both my team and me. What immediately caught my attention was the visual editor. As a marketer, having a true what-you-see-is-what-you-get (WYSIWYG) interface makes creating and editing pages far less stressful. And Storyblok does exactly. This allows the marketing and editorial team to easily add content the way we want with reusable content blocks. 

I really enjoy the preview that we can configure to the system. It's particularly helpful as it allows my team to see how my updates will look in real time across multiple channels. Also, I'd say Storyblok's collaborative feature is on par with Sanity. I can tag, comment, and reply to a task right there. 

Given these capabilities, Storyblok is one of the best headless CMSes to work with if you need to build multiple landing pages quickly for your website. 

From a technical perspective, Storyblok’s biggest strength is its component-based architecture. My web development team has been able to build reusable content with blocks of multiple components. Once they set up the required content types and components, we can start adding and managing our content independently without breaking anything. 

Localization is another area where Storyblok pulled its weight. Several G2 reviewers manage content across many markets and languages and the folders, roles, and workflows make it easy to keep brand and country-specific content organized while configuring global settings just once. With built-in AI translation now part of the mix, rolling content out across regions felt far less manual than it used to.

I'd also call out two things that quietly make day-to-day work smoother: support and assets. I see a lot of praise for how responsive and genuinely invested Storyblok's support team is, even as the company scales. And the built-in asset CDN—with focal points and scheduled publishing—meant my team didn't have to worry about hosting media or timing releases by hand, which is a real plus when content has to go live at a precise moment.

From what I heard from them, the platform integrates well with frameworks like Vue, Next.js, Astro, and Nuxt, making the development process smooth and efficient no matter what stack we’re using.

Storyblok has a lot to offer, but a few areas could use refinement. One of my web engineers found the JavaScript libraries a bit clunky compared with other platforms, a sentiment echoed by some G2 reviewers, and I've hit the occasional hiccup with asset uploads on media-heavy content. Still, these are edges rather than dealbreakers: the managed asset CDN works smoothly once content is in, and the visual editing experience more than makes up for the rare rough spot.

Pricing is another consideration. Storyblok leans premium, and for small teams or personal projects it can feel like more than you need; G2 users have also noted that lower tiers lack robust backup options, which can be limiting for critical work and needs a workaround via the API. But for mid-sized businesses and enterprises with serious content needs, the capability you're paying for genuinely earns its keep.

However, for mid-sized businesses or enterprises with robust content needs, it’s a solid investment. Minor cons aside, there’s no denying that their CMS is the real star, it’s what you come for, and it’s what they truly excel at. 

What I dislike about Storyblok:

• On lower-tier plans, there's no option to back projects up directly to an S3 bucket (or similar); you have to work around it with the API, which is worth knowing for critical work.
• My developers felt the JavaScript libraries and advanced-feature tutorials could be stronger — though the core editing tools are excellent, and once you're set up, the day-to-day experience runs smoothly.

What G2 users dislike about Storyblok:

"The plugin marketplace still has room to grow, and a couple of bulk actions need to be improved. You have to go on the hunt for some really good community plugins. They exist, but it's difficult to find them if you are not on Discord and the community hubs."

- Storyblok review, Benedikt G. 

3. Hygraph: Best for GraphQL native structured content

I’ll admit that I have a real appreciation for a well-thought-out interface, and Hygraph definitely delivers on that front. It’s one of those platforms that just feels good to use—everything is responsive, and well-organized in a way that makes managing content feel less like a chore.

From what I heard from my web developer team, Hygraph’s GraphQL API is rock solid. The API is incredibly fast, and querying content is a smooth experience, especially when working with large datasets. My team appreciates how well it integrates with modern frameworks like Next.js and Astro, allowing us to build highly dynamic frontends with minimal friction. We’ve built some pretty complex content models, and Hygraph handles them effortlessly.

Another notable aspect for us has been webhooks. My team was able to automate multiple options, from triggering Slack notifications for new leads to sending email alerts when a fresh blog post goes live with them. 

Beyond the developer side, Hygraph turned out to be approachable for non-technical teammates too. Several reviewers described setting up and managing a blog or landing pages in minutes with little to no learning curve, and one marketing team noted they could edit pages without pulling in product or engineering. For me, that meant less time maintaining a custom CMS and more time actually publishing.

I also appreciated working with a true content repository rather than thinking in pages and templates. Reviewers highlighted how Hygraph lets you structure content once and reuse it across channels and campaigns without inconsistencies, and publish or update entries without waiting on engineering. That reusable, block-based approach kept our messaging consistent everywhere we publish.

Value was another pleasant surprise. While costs can climb as you scale (more on that below), multiple reviewers called the free and lower tiers genuinely generous, with multi-user access included rather than locked to a single seat. It also integrated cleanly with tools like Vercel and tied neatly into back-office systems, which made setup and handover fast.

Media handling deserves a mention of its own. Reviewers singled out Hygraph's asset management, being able to upload a wide range of formats (WebP, PNG, JPEG, GIF, MP4) while keeping images crisp without bloating file sizes, and having every uploaded asset visible and easy to retrieve in one place. I can be the fix for a long-standing problem with oversized images, and for a content-heavy site, that reliable asset layer kept our pages consistent and fast.

On pricing, Hygraph sits between Sanity and Storyblok. Its free plan is generous, but user caps and API call limits can become a bottleneck, costs can climb quickly as a project scales, and features mid-to-large enterprises need—custom roles, granular permissions—sit behind higher tiers. The upside is that the lower tiers are genuinely reasonable and multi-user friendly, so for most small and mid-sized projects you get strong value long before you hit those ceilings.

I also found the documentation a little thin once you move past the basics, onboarding gets harder with complex content models or advanced queries, and other G2 reviewers describe the same gap. That said, the support team came up repeatedly as quick and responsive (often same-day), which reliably helped bridge the moments where the docs left off.

Nonetheless, I'd say Hygraph is a great fit for teams that need a CMS built around flexibility, customization, and a GraphQL-first approach.

What I dislike about Hygraph:

• The documentation could be better for troubleshooting and onboarding; I sometimes had to piece solutions together from several sources.
• Costs can climb fast on larger or high-traffic projects, so it's worth planning for — but the generous lower tiers mean you get real value before scaling ever pushes you up a plan.

What G2 users dislike about Hygraph: 

 "The Hygraph Studio interface can sometimes be a bit buggy (doesn't show full error messages of what to fix and why it needs to be fixed). The documentation isn't as detailed for complex or advanced integration. For complex projects, it can be a bit hard to find the field you want to edit and to know what edits it will cause."

4. Contentstack: Best for enterprise-grade governance, automation, and scalability

I've heard a lot about Contentstack before but this was the first time I explored it fully. Contentstack strikes a balance, it’s structured, API-driven, and built for teams managing complex workflows.

If Sanity has Studio and Storyblok has its Visual Editor, Contentstack’s answer to them is its Visual Builder, a WYSIWYG interface that lets me create, manage, and edit pages in real-time—without getting stuck in a rigid template structure. The drag-and-drop blocks are a lifesaver, allowing me to use developer-created content components while still having the flexibility to arrange and customize pages.

One of my favorite features is preview sharing. It’s such a small thing, but having an external preview link that I can send to stakeholders without requiring them to log in is a huge time-saver.

Another noticeable aspect to me was how well it handles multi-team collaboration. With built-in SSO, role-based permissions, and structured workflows, it’s clear this platform was designed for organizations where content isn’t just published—it goes through layers of approvals, edits, and governance. Their tasks features like tag, comments.

From a technical standpoint, Contentstack includes everything and more of what other CMS tools offer. My developers highly value its robust API ecosystem, with its Content Delivery API, Content Management API, image API and GraphQL API, making content retrieval and management easy across platforms.

The modular content approach was the biggest win my team kept coming back to. Reviewers running large, frequently-changing sites described reusing components across pages and launching updates quickly without heavy developer involvement, spinning up event or campaign pages fast while keeping everything structured and consistent. For high-volume sites, that speed without chaos is exactly what you want.

Contentstack also proved itself for global content operations. Some manage content across roughly 25 languages and credit the platform with keeping it all structured and quick to publish, while others pointed to scheduled publishing for precise, low-risk releases and version comparison for tracking exactly what changed. For enterprise teams juggling many locales and release windows, those governance touches add up.

Contentstack offers powerful content modeling, but with a few usability snags. Editing inside complex templates — clicking through blocks, sub-sections, and nested elements — can feel more involved than it should, and G2 reviewers managing large or deeply structured content note the same. Even so, that depth is exactly what lets the modular, reusable components keep big sites consistent and fast to update, so the trade-off largely works in your favor once the structure is set.

I've also seen occasional slowness loading large content lists; it's not a blocker, but the lag adds up at high volume, and G2 feedback flags it as a common theme. To be fair, it's been improving, reviewers credit steady UI and search enhancements over the past couple of years, and the responsive support plus quick publishing mean it rarely gets in the way of actually shipping content.

What I dislike about Contentstack:

• Editing complex templates with lots of fields can be cumbersome, and it's easy to click through several layers just to make a small change.
• It can be slow loading large content lists at times — but it's been steadily improving, and the modular setup plus responsive support keep it from slowing the team down for long. 

What G2 users dislike about Contentstack: 

"It's been hard to create templates that work the way that we want them to work. It creates a little bit of extra time because we don't have these templates. We have engineers who work on it who haven't cracked the right way to create templates. So sometimes we have to start things from scratch instead of other solutions where we've been able to draft templates and build out these workflows faster."

- Contentstack review, Kevin R. 

5. Prismic: Best for content modeling with flexibility

Prismic has been one of the more user-friendly headless CMS platforms I’ve worked with. Right from the start, the interface feels approachable—everything is clean, well-organized, and easy to navigate, like Hygraph, but in a different way. 

One of the standout features is Slices, which are Prismic’s take on reusable content blocks. My developers can create flexible sections—like text, images, videos, or custom components and I can arrange them freely across different pages in the way I want.

A recurring thread in the reviews shows how much Prismic has matured as a product, and how steadily it keeps improving. Reviewers who've used it for a year or more described meaningful quality-of-life upgrades arriving regularly like cloning slices with a literal copy-paste, inserting a new section between slices without dragging everything into order, and edits that no longer bounce you to a different part of the page on save. The team actively listened to feedback and shipped accordingly, which gave confidence to scale projects on Prismic as a long-term bet. For me, that kind of momentum matters as much as any single feature.

This is great for content teams because it means I can mix and match elements without having to rely on developers for layout changes. It’s especially useful when working on multi-page designs, where I need the freedom to make updates quickly while keeping the structure consistent.

However, according to my web development team, what really takes this a step further is Slice Machine, Prismic’s development tool. This tool lets them create and manage Slices locally. My developers thoroughly enjoy that it lets them work in their own environment, building components directly in code and syncing them with Prismic. It speeds up our workflow.

From a developer’s perspective, Prismic integrates well with modern frameworks like Next.js, Nuxt, Sveltekit and the API responses are good. The GraphQL support is solid, and my team likes how they can define content models in a way that fits the project, rather than being locked into a rigid backend structure.

Prismic's Slices give content teams real flexibility, but it has a few quirks. One is the inability to mark fields or slices as mandatory, so I end up manually double-checking that key content is present on each page—a small but recurring hassle other G2 users have raised too. Still, it's a minor gap against an otherwise clean, intuitive editing model, and the consistency Slices give you across pages more than offsets the occasional manual check.

The rich text editor also has limits, no text color, so highlighting means a custom tag, and no native nested lists, which pushed us to build a custom Slice for nested bullets. That's more effort than such basic formatting should need. On the brighter side, Prismic has been closing gaps like this fast: reviewers consistently note steady, meaningful updates, so today's limitation is often tomorrow's shipped feature.

Even with these drawbacks, I'd say Prismic is a solid choice for teams that prioritize speed and simplicity in content management. If you're frequently launching marketing campaigns, landing pages, or promotional content, you can definitely consider Prismic. 

Even for hobby sites and small projects, Prismic has a good free plan, right on par with Sanity, if not better than that. 

What I dislike about Prismic:

• The rich text editor's limits (no text color, no native nested lists) meant leaning on developers for custom tags and slices just for basic formatting.
• There's no built-in way to mark fields or slices as mandatory, so it's easy to miss key content — though it's a minor gap in an otherwise clean editor, and Prismic ships updates often enough that fixes like this tend to land.

What G2 users like about Prismic: 

"Some features feel a bit hidden at first, and it can take a moment to understand how slices and custom types are structured. Once you get used to it, it works well, but the initial learning curve could be smoother."

6. Umbraco: Best for .NET-based solutions with full customization

If you've been in web development for a while, I'm sure you've heard of Umbraco, the open-source CMS known for its flexibility and developer-friendly approach. What surprised me was discovering that Umbraco also offers a headless CMS version called Umbraco Heartcore, which wasn’t on my radar until I started researching options.

I’ve always known Umbraco as a powerful .NET-based CMS, exploring the capabilities of its headless CMS was interesting. I know a couple of developers who have customized Umbraco's open-source CMS in itself as a headless CMS. It's that flexible. But having a dedicated headless version means you get the same flexibility without some extra work.

From what I understood, it takes what developers love about Umbraco—its customizability, structured content management, and deep .NET integration—and packages it into an API-first platform that’s ready to deliver content wherever you need it. 

One of the biggest advantages I’ve noticed is how well it integrates with existing .NET ecosystems. If your tech stack is already built around Microsoft technologies, Heartcore fits in like a glove. The GraphQL and REST APIs work well, making it easy to fetch structured content.

What surprised me most in the reviews was how often non-technical users praised Umbraco's editing experience. Reviewers repeatedly described it as intuitive and easy to learn, where people with no CMS background picking it up with little training, and teams delegating editing rights across the organization. For a platform with such deep developer roots, that approachability for everyday editors is a genuine strength.

Security and stability also came up consistently. Reviewers called Umbraco a stable, mature product and praised how quickly the team patches the occasional security issue. For client and charity sites that need to stay up and trustworthy, that reliability mattered—it's not the flashiest selling point, but it's one I'd weigh heavily.

Finally, its integration and localization capabilities round things out. 2026 reviewers connected Umbraco to systems like Salesforce, Stripe, and Google Analytics, and global teams used it to host multiple instances with region-specific, translated content across many cultures. That flexibility to plug into an existing stack and serve multiple markets makes it a strong fit well beyond just .NET shops.

Another highlight for me is its active online community. There’s no shortage of developers sharing knowledge, contributing to forums, and providing guidance on best practices. Whenever our team runs into an issue or needed advice, I’ve found answers quickly there. 

Heartcore brings the flexibility and power you'd expect from Umbraco, along with some of its quirks. The initial setup isn't exactly plug-and-play, and it leans on developer support both at the start and for ongoing updates. But that's the flip side of how customizable it is, once configured, that same flexibility is what lets you build almost exactly the site and workflows you want, with very little you can't tailor.

Documentation is the other challenge. The basics are covered, but key topics felt underexplained, and building more complex solutions meant some trial and error, something other users echo. What saves it is the community: Umbraco's developer network is large and active, and between forums, tutorials, and third-party resources, I've consistently found answers quickly even where the official docs fell short.

So, who is Umbraco best for? If you’re looking for a CMS that offers deep customization, enterprise-level scalability, and seamless .NET integration, Umbraco is a fantastic choice, from my perspective.

What I dislike about Umbraco:

• The documentation could be more comprehensive; key topics aren't always well covered, which can mean some trial and error.
  It's not the most beginner-friendly setup, and being .NET-based it fits.
• Microsoft stacks best — but the large, active community fills the gaps quickly, and that same flexibility is exactly what makes it so powerful for complex builds.

What G2 users dislike about Umbraco: 

"Umbraco is powerful, but the learning curve can be steep for new users, especially for developers unfamiliar with .NET. Some features that are easy in other CMSs require extra setup or customization here."

- Umbraco review, RAJKUMAR M. 

7. Prepr CMS: Best for built-in personalization and A/B testing

I came across Prepr CMS while hunting for a platform that wouldn't force me to bolt on a separate optimization tool just to test a headline, and it quickly earned a spot on this list. It's a headless CMS aimed squarely at marketing and growth teams who treat their website as a conversion engine rather than a static brochure. Across the recent G2 reviews I dug into, the same picture kept emerging: a platform that content editors find approachable and developers find flexible, backed by a team that's clearly shipping improvements at a steady clip.

What makes Prepr stand out from everything else on this list is that it folds content management, A/B testing, and personalization into a single platform. As a marketer, that's a big deal—I'm not stitching together a CMS, an experimentation tool, and a personalization engine and praying they talk to each other. I can spin up content variants, target them to a segment, and measure what's converting without ever leaving the tool. Several G2 reviewers framed this as an affordable alternative to enterprise platforms like Sitecore or Optimizely when you specifically need testing and personalization baked in.

The Visual Editor is the feature I leaned on most. Like Storyblok and Contentstack, Prepr lets me draft, adjust, and preview content live before anything goes public, which takes the guesswork out of campaign updates. G2 reviewers in early 2026 repeatedly singled this out, with one agency noting their clients could draft and preview changes without touching anything live—giving non-technical stakeholders the confidence to work independently.

Ease of use is where Prepr really wins over content teams. The interface is clean and lightweight, the initial setup was described again and again as "super easy," and the shared media library keeps assets consistent across pages. For my team, that translated to less training time and fewer support tickets after handover—a recurring benefit reviewers called out when handing platforms off to clients.

On the technical side, my developers appreciated that Prepr is API-first with both REST and GraphQL, and the clean GraphQL layer drew consistent praise in recent reviews. A detail that came up more than once was the flexibility of mixing content Models and Components inside a single Stack field, plus the ability to drop blocks directly into content fields. The Next.js package handled most of the heavy lifting, and spinning up a test environment was straightforward thanks to the ready-made environments Prepr provides.

There's also a growing layer of AI assistance that reviewers talk about, including help with translations and content optimization. It's not the deepest AI tooling on the market yet, but it's already useful for speeding up multilingual work, and editors noted it as a genuine time-saver inside their day-to-day workflow. 

Finally, the support experience is a standout. Reviewers mentioned getting direct, personal contact with the team during setup, no cumbersome enterprise ticket queues, just people who think along with you. My own experience echoed this; small issues got resolved quickly, which matters a lot when you're committing a whole team to a new platform. 

Content navigation can get harder as your library grows, on large implementations with a high volume of items, reviewers noted the search experience could be more powerful. That said, on small to mid-sized projects, it's smooth and intuitive, and the friction is largely avoidable: structure your content model thoughtfully upfront, and the scaling issue mostly takes care of itself. 

The editing surface also has its quirks; developers described it as long, stacked input forms, wished for a CLI rather than a web-only configuration, and missed schema-based cloning and version control of the kind Sanity offers. Even so, this is clearly a platform in motion: reviewers consistently credited the team with shipping new features and improvements, the emerging AI tooling is already chipping away at the manual parts, and the responsive support means the rough edges rarely turn into roadblocks.

All things considered, Prepr CMS is a genuinely compelling pick if you're a marketing or growth team that lives and breathes campaigns, testing, and personalization. It gives developers the structured, API-first foundation they want while giving marketers real control over experimentation, without a pile of add-on tools.

What I dislike about Prepr CMS:

• On larger libraries, search and navigation feel underpowered, and I found myself wishing for a faster way to locate specific entries.
• The editing surface is mostly long, stacked forms, with no CLI yet and no schema-based cloning like Sanity's — but the team ships improvements constantly, and the emerging AI tooling plus quick support keep these from turning into real blockers.

What G2 users dislike about Prepr CMS: 

"From a developer's perspective, configuration of the CMS is mostly done via web views. It would be great if the configuration could be consolidated more. This is now done throughout the web portal, while a specific developer segment or maybe even a CLI tool would speed up development, especially with the rise of agentic AI."

Now, there are a few more options, as mentioned below, that didn't make it to this list but are still worth considering, in my opinion:

• Contentful: Best for developer-friendly omnichannel delivery and multi-language content at enterprise scale. 
• Kontent.ai: Best for enterprise-level modular content and collaboration.
• Optimizely Content Management System: Best for marketer-friendly composable content with built-in experimentation and personalization.
• Bloomreach: Best for AI-powered search, merchandising, and content personalization.

Best headless CMS software: Frequently asked questions (FAQs)

Q1. How does a headless CMS differ from a traditional CMS?

A traditional CMS handles both content and presentation. A headless CMS, on the other hand, manages only the content and delivers it via APIs, letting developers use any frontend tech (like React, Next.js, or Vue.js) to create custom digital experiences.

Q2. Who should use a headless CMS?

Headless CMS is ideal for enterprises managing multi-platform content, e-commerce brands needing fast API-driven setups, developers wanting frontend freedom, and marketers aiming for seamless omnichannel delivery.

Q3. What are the best headless CMS platforms?

Leading headless CMS platforms include Contentful for enterprise needs, Sanity for real-time collaboration, Storyblok for its visual editor, Hygraph for GraphQL projects, and Strapi for open-source flexibility.

Q4. How do I choose the right headless CMS?

Key factors include ease of use (e.g., visual editors vs. dev-focused tools), API flexibility (GraphQL/REST support), scalability for enterprise needs, and pricing based on usage, users, and storage.

Q5. What are the best open-source headless CMS options?

Top choices include Strapi for full customization, Directus for SQL database flexibility, Payload CMS for a JS/Node.js stack, KeystoneJS for GraphQL/React projects, and TinaCMS for Git-based content editing.

Q6. Can I use WordPress as a headless CMS?

Yes, WordPress headless CMS setups are possible using the WordPress REST API or WPGraphQL. This allows WordPress to act as the backend while using a modern frontend framework like Next.js, React, or Vue. However, this approach requires more developer effort compared to using a native headless CMS.

Q7. Is a headless CMS good for eCommerce?

Yes, a headless eCommerce approach is increasingly popular. A headless CMS allows businesses to manage content separately from the eCommerce backend, providing more flexibility in designing product pages and personalized shopping experiences. Popular headless CMS platforms integrate with Shopify, Magento, BigCommerce, and other eCommerce platforms.

Q8. How does a headless CMS handle content localization?

Most headless CMS platforms have built-in localization features, allowing users to manage multilingual content efficiently. Instead of duplicating pages, you can store multiple language versions in a single content entry and serve the correct version based on user location. Contentful, Sanity, and Storyblok offer strong localization tools.

Q9. What are the best cloud-based headless CMS solutions?

Nearly every leading headless CMS is cloud-based (SaaS), meaning the vendor hosts and scales the backend for you. From the platforms in this guide, Sanity, Storyblok, Hygraph, Contentstack, Prismic, and Prepr CMS all run as fully managed cloud services, so you get automatic updates, CDN-backed delivery, and no servers to maintain. Umbraco Heartcore is the cloud-hosted headless version of Umbraco for teams that want the same model within a .NET ecosystem.

Q10. What are the best headless CMS platforms for omnichannel publishing?

Because a headless CMS separates content from presentation and serves everything through APIs, it's built for omnichannel by design—the same content can flow to a website, mobile app, or other touchpoints without duplication. Storyblok, Contentstack, and Contentful stand out here for delivering consistent content across multiple channels through REST and GraphQL APIs, while Prepr CMS adds personalization on top so each channel can be tailored to the audience.

Q11. What are the best tools for secure headless content delivery?

Security comes down to access controls, encryption, and compliance. Look for role-based access control (RBAC), single sign-on (SSO), and certifications like SOC 2 or GDPR compliance. Contentstack is frequently noted for enterprise-grade governance and robust RBAC, and most enterprise-focused platforms in this list offer SSO, granular permissions, and data encryption—though some lock advanced permission tiers behind higher-priced plans.

Q12. What is the top headless CMS for scaling global content delivery?

For global scale, prioritize CDN integration, caching, and strong localization. Contentstack and Contentful are well suited to large, multi-region content operations, with Contentful in particular known for handling multi-language content from a single entry rather than duplicating pages. Sanity and Storyblok also offer solid localization tools for teams managing content across markets.

Q13. What are the top tools for decoupled content management?

"Decoupled" and "headless" are closely related—both separate the content backend from the frontend presentation layer. All seven platforms in this guide (Sanity, Storyblok, Hygraph, Contentstack, Prismic, Umbraco Heartcore, and Prepr CMS) follow this API-first, decoupled approach, letting developers build the frontend with modern frameworks like React, Vue, or Next.js while editors manage content independently.

Q14. What is the top-rated headless CMS for developer flexibility?

Developer flexibility usually means framework freedom, strong APIs, and extensibility. Hygraph is a standout for GraphQL-native projects, Sanity for deep schema customization, and Umbraco Heartcore for teams invested in the .NET ecosystem. Prismic's Slice Machine and Prepr CMS's API-first setup also score well with developers who want to build components in code and sync them to the CMS.

Q15. Which headless CMS offers AI-driven content recommendations?

AI capabilities are expanding fast across the category. Bloomreach is built around AI-powered search, merchandising, and content personalization, while Contentful and Optimizely's CMS both layer native AI into content creation and personalization. Prepr CMS also offers AI assistance for tasks like translations and content optimization, with more features rolling out over time.

Q16. Which is the best headless CMS for enterprise content delivery?

For enterprise needs—governance, scale, and multi-team workflows—Contentstack is a strong pick thanks to its SSO, RBAC, structured approval workflows, and broad API ecosystem. Contentful and Optimizely's CMS are also enterprise-oriented, offering composability, AI, and reliability for large organizations delivering content across many channels.

Q17. Which platform offers the fastest API response times for CMS?

API speed depends heavily on your setup, caching, and CDN, so real-world results vary. That said, platforms with CDN-backed GraphQL delivery tend to perform well: Hygraph is frequently praised for its fast, reliable GraphQL API even with large datasets, and Sanity's REST and GraphQL APIs are noted for quick content fetching. The best approach is to test response times against your own content volume during a trial.

Headless, but not clueless

If there’s one thing I’ve learned, it’s that not all headless CMS platforms actually work for both developers and content teams, despite what they promise. Some have powerful APIs but need heavy customization to improve the editorial experience. Others strike a better balance between flexibility and usability. Open-source options like Strapi and Directus give you total control but require more hands-on maintenance.

But more than this, going headless completely changes how you structure content on your site. I didn’t fully grasp that until I worked with these tools myself—the way entries, fields, content types, and APIs are handled can make or break your workflow.

So if you’re choosing a headless CMS, don’t just look at features. Think about how your team actually works and what kind of content you publish. The right CMS is the one that makes content management easier for your whole team. And if you’re anything like me, you’ll probably go through a few before you find the one that truly fits how your team works.
