We defend and believe in Open Source and proof of this is that our main project, Penpot, reflects that. We’re convinced that technology isn’t neutral. That’s why we like to shake things up and go against the status quo .

Penpot is the free open-source design tool that allows true collaboration between designers and developers. Penpot is one of the most promising global design tools for interaction design used by hundreds of thousands UX/UI designers, Product designers and web developers across the world.
