Enabling access to remote desktops, laptops, and operating systems is one of the best ways to remain secure within a network.

This process is called virtualization and is possible through the use of virtual desktop infrastructure software, also known as VDI.

But despite the security benefits, VDI software isn’t necessarily known for its affordability.

For developers with virtual desktop infrastructure use cases looking for virtualization on a budget, we compiled an in-depth analysis of the best free VDI solutions to look for in 2019.

The products listed above are either free versions of enterprise offerings or open-source solutions to host yourself. Either way, let’s get into each VDI solution in more detail.

The project began at the University of Cambridge more than a decade ago. Now, it powers the core of many enterprise-grade virtualization such as Citrix XenDesktop.

Features: Xen typically hosts Linux guests, but there are drivers for additional operating systems. It boasts consumer-grade simplicity through a Windows Continuum experience on any device, consistent user experiences, rich support for ChromeOS, automated client config plus selection of best path, and Web-based self-service password reset.

What users are saying: G2 Crowd users have said it’s simple, effortless to set up, flexible, and powerful. XenDesktop is a commercial application but does have overwhelming support visible through its many reviews.

2. flexVDI

flexVDI is an open-source solution developed in Zaragoza, Spain. It powers VDI for major European entities such as BBVA and the Spanish government. Keep in mind, only some components of the flexVDI ecosystem are free and open-source, so be cautious when evaluating costs.

Features: flexVDI supports Microsoft Windows operating systems and “all flavors” of Linux distributions. It boasts an improved version of the fully open-source protocol named SPICE, flexibility across many devices, developer friendliness via JSON API, and transparency through its public repositories on GitHub.

What users are saying: G2 Crowd users have said it’s simple and affordable compared to other options. flexVDI is also renowned by users for its ease-of-use when configuring and starting up the product.

3. Amazon WorkSpaces

Amazon WorkSpaces is a secure desktop computing service that runs on the powerful AWS cloud. Fortunately for users, there is a free version of this VDI solution – granting two bundled workspaces with a usage of 40 hours per month.

It’s worth noting that this offering only lasts for the first two months. So if you find it helpful, you can upgrade and continue using at the scale you desire.

Features: Amazon WorkSpaces allows provision cloud-based virtual desktops and provides users access to the documents, applications, and resources needed from any supported device. This includes Windows and Mac computers, Chromebooks, iPads, Fire tablets, and Android tablets. The two workspaces come in the form of a fully managed desktop-as-a-service (DaaS) solution running on AWS.

What users are saying: G2 Crowd users have said it’s arguably the best solution for those who travel frequently or are always on-the-go. The flexibility of devices is also a major plus, according to users.

4. Hyper-V

Hyper-V, surprisingly, features a free tiered VDI solution which allows users to build fully functioning Hyper-V host servers without paying licensing fees.

It’s worth noting that if you want to avoid paying licensing fees, you won’t be able to host Microsoft Windows accounts, but you could run Linux Guest.

Features: Hyper-V has a wide range of features. This includes nested virtualization for testing purposes, host resource protection to prevent CPU and RAM from being taken up by one virtual machine, PowerShell direct for admins, storage replica for volume replication, and much more.

What users are saying: G2 Crowd users have agreed Hyper-V is one of the most stable VDI solutions out there with a user-friendly setup and configuration. Others state it’s a phenomenal alternative to VMware.
