Open source UX software

As a passionate user of open source software for almost two decades, I prefer to use only open source software during the design process (but I'm pretty flexible during a professional project). Below you can find the best open source UX software available today.


Inkscape is a vector graphics application with which you can make user personas, customer journey maps, user flow diagrams, moodboards, wireframes and high-fidelity designs. It's a very complete application with a gazillion number of features. It can easily match proprietary software like Adobe Illustrator (you can watch a complete comparison between the two here).

A new contender in the world of open source UX software is the application Penpot (previously known as UXBOX). It promises to be a complete open source solution for creating interactive prototypes. As it fully embraces open standards like SVG, it will help you prevent the vendor lock-in effect that you have with proprietary software. It's developed by the company Kaleidos, the company that also develops the project management application Taiga.

Quant UX

Another new contender in the world of open source UX software is Quant UX. The biggest selling point of Quant UX is that it allows you to create interactive prototypes that you can test and analyse immediately. Quant UX has a built-in screen recorder, offers a heatmap and has the ability to do A/B testing.

Presentator is a simple, yet effective, application to turn high-fidelity images into an interactive design. With this application it's easy to add clickable areas (links) to an image in order to go from one image to another. Because it's open source you can install it on your own server and this is what I did: if you look closely to addresses of the interactive mockups (see here, here and here), you can see that Presentator is installed on a subdomain of this website.

At the moment there doesn't exist a native prototyping tool for Linux but that's about to change with the development of the application Akira. It's still in early development but the development is active and a stable release is to be expected in 2021. Because it will use GTK as its native toolkit, it will integrate nicely with the Linux desktop.

A demo of the alpha release can be found here.
