Penpot calls itself an open-source design platform for teams. It describes itself as an open-source design platform for teams, with a free sign-up and a self-host install option. That choice matters if you want your design files on servers you control, so decide which route fits your team before you move.

On its home page Penpot lists wireframes, interactive prototypes, and layouts built with CSS Grid and Flex. It also lists design components, native design tokens and shared libraries for design systems. For handoff it points to open standards such as CSS, HTML, SVG and JSON, plus its own open file format.

When you switch from any design tool, test a real project first. Check that your fonts, components and prototypes survive the import, that developers can read the specs they need, and that you can export your files in a format you can open elsewhere. Decide who needs editing rights and who only needs to view, and agree where the files will be stored before you invite the team.
