Open‑source design tool, an alternative to Figma. Supports vector design, prototyping, and real‑time collaboration. Self‑hostable, with a free cloud tier.
Penpot is an open‑source UI/UX design tool similar to Figma. All code is open‑source, and you can self‑host. It offers vector design, component libraries, prototyping, and real‑time collaboration—completely free.
I designed a web prototype on Penpot cloud, collaborating smoothly with a colleague. The component system felt familiar to Figma. Since it’s open‑source, I could self‑host later if I wanted to avoid vendor lock‑in.
Penpot is the best choice for privacy‑conscious teams, with functionality rivaling commercial tools.
Pro tip: Penpot imports Figma files (.fig), so you can migrate existing projects easily.
