Who it's for

Designers and developers on product teams who need real-time collaborative UI/UX design and prototyping, especially teams that want a self-hosted alternative to proprietary tools like Figma or Adobe XD.

What you get

A full design and prototyping tool for responsive UI design, wireframes, and interactive prototypes, with CSS Grid/Flex-based layouts, reusable components, and design tokens for building design systems. Files are stored in an open, SVG-based format, and designs can be inspected as CSS, HTML, and JSON for handoff to developers. It's free and open-source, usable via Penpot's cloud or self-hosted on your own infrastructure.

How it works

Sign up on Penpot's cloud or self-host it, then create a project and design directly in the browser using boards, layers, and components, with multiple users editing the same file simultaneously. Interactions between screens are added to build clickable prototypes, and the underlying code (CSS/HTML/SVG) can be inspected or exported for implementation.
