9 best free flow chart software tools I recommend 

The market for flowchart software is growing faster than ever as companies adopt more visual, collaborative ways to map processes and improve efficiency. By 2025, the global online flowchart software market is projected to reach $1.49 billion, growing at a strong 12.88% CAGR through 2031 as enterprises intensify their focus on visual process optimization and real-time collaboration.

And after trying several options myself, I’ve learned that you don’t need a paid plan to build clean, professional flow diagrams. Many free flowchart software options go far beyond the basics, offering intuitive editors, ready-made templates, and real-time collaboration that seamlessly integrates into a team’s workflow.

These tools have made it easier for me to break down complex processes, share ideas visually, and keep projects aligned without adding another expense to the tech stack.

How did I find and evaluate these free flow chart software tools?

To build this list, I started with G2 data, shortlisting the top-rated flow chart and diagramming tools based on their G2 scores, category standing, and consistent performance in the Free Flow Chart Software category.

 

From there, I dug into product feature sets and recent, verified user reviews to understand how each tool performs in real workflows, what users genuinely love, and where each product shines. This helped me identify which platforms offer genuine value, rather than just impressive marketing.

 

Since this is a free-focused list, I also paid special attention to what you can actually do on the free plan: whether the free tier includes core flow chart features, the limitations you might run into, and whether a free trial gives enough time to test advanced tools without committing.

 

The screenshots featured in this article may be a mix of those taken from the vendor’s G2 page or from publicly available materials.

The free flow chart software list below contains user reviews from the best diagramming software category page. It’s important to note that in the context of this list, vendors that offer a free trial are considered free. To be included in this category, a solution must:

  • Offer targeted tools for designing one or more types of diagrams, such as organizational charts and floor plans
  • Provide industry-related shapes and elements for use in diagrams 
  • Allow users to create or import custom diagram components
  • Allow specific users to view and interact with diagrams online during and after presentations

This data was pulled from G2 in 2025. Some reviews may have been edited for clarity. 

1. Cacoo: Best for collaborative team diagramming in the cloud 

Overcome all your diagramming challenges with Cacoo! This cloud-based tool allows you to collaborate with your teammates from any device with an internet connection.

Cacoo

Pros and cons of Cacoo: What stood out to me

Pros of Cacoo Cons of Cacoo

Wide variety of pre-built shapes library Limited customization compared to advanced diagramming software

2. Cloudcraft: Best for flow-chart-style AWS infrastructure diagrams

You can see your resources, connections, and estimated costs in one place. CloudCraft helps you design, document, and manage your AWS architecture.

Cloudcraft

Pros and cons of Cloudcraft: What stood out to me

Pros of Cloudcraft Cons of Cloudcraft
Effortless AWS visualization Only designed for AWS cloud infrastructure
Real-time synchronization Limited diagramming features beyond AWS
3D view and clear visuals Primarily focused on visualization and documentation
What G2 users like about Cloudcraft:

“The 3D view and integration with AWS (including the synchronization feature) make it incredibly easy to visualize and maintain your cloud infrastructure in real-time. As a cloud architect, I've tried many tools, but none of them have had the impact that CloudCraft diagrams produce on clients. They remain amazed at how much they can see about their existing or proposed infrastructure. It's also a fantastic tool for teaching about AWS cloud infrastructure and services.”

- Cloudcraft Review, Walter J.

What G2 users dislike about Cloudcraft:

“It's a bit difficult to use the user interface on a laptop due to the trackpad. I always prefer using a physical mouse. Also, if they could provide suggestions based on the resources I use in my architecture diagram, that would be a great feature.”

- Cloudcraft Review, Aman M.

- Creately Review, Surya Prakash M.

What G2 users dislike about Creately:

“The least helpful aspect of Creately might be its limited functionality in the free plan, which may restrict users from fully experiencing the platform's capabilities without upgrading to a paid subscription. Next is its dependency on an internet connection. Since Creately is a cloud-based tool, it requires a stable internet connection to access and work on diagrams. This dependency on internet connectivity may pose challenges for users in areas with poor internet infrastructure.”

6. Miro: Best for visual collaboration and scalable flow charting

Miro goes beyond basic flow charts. It's a sprawling digital canvas for brainstorming, teamwork, and project tracking.

Pros of Miro Cons of Miro
Visual collaboration Steep learning curve with advanced features

Flow chart template library Limited storage with the free plan
What G2 users like about Miro:

“First, I like the scalability of MIRO Whiteboards. You can quickly start with a small drawing and add more and more information, pictures, notes, and references to it. You can also end up with a large-scale drawing that still works and provides a decent overview of what you did. As a proper cloud-based solution, these results are available everywhere: on your PC, in the home office, virtually, and even in real-life meetings. So, results are not lost but can be reused and enhanced in collaboration. That’s the way I love to use whiteboards.” 

- Miro Review, Detlev P.

What G2 users dislike about Miro:

“Though it's a must-have for marketing and salespeople, designers, developers, and project managers may sometimes find that too many things overwhelm it. Also, integration with Zoho apps is missing. And when I add comments, I need to manually link each comment to the elements, which is very frustrating. I wish there could be an easier way to do this.”
