What is Penpot?

Penpot is a web-based design and prototyping platform that is fully open source, which means teams can use its hosted version free or run it on their own servers. It covers the essentials of interface design: vector editing, components, shared libraries, layout with flex and grid, and interactive prototyping. Because designs live in open formats like SVG, handoff produces inspectable code and styles.

Penpot's community drives development, and recent releases have closed much of the gap with commercial rivals on tokens, variants, and developer tooling. Performance on very large files and the smaller plugin ecosystem still show its indie roots. For organizations that need data control, public institutions, and budget-conscious teams, Penpot is the credible free alternative to subscription design tools.
