Penpot is an open-source design and prototyping platform created by Kaleidos, a software company from Spain, and developed as the leading open-source alternative to Figma. It runs in the browser, supports real-time collaboration and stores designs in open standards: shapes are SVG and layouts map directly to CSS flexbox and grid, which makes handoff to developers more predictable.

Penpot 2.0, released in 2024, brought a new component system and CSS grid layout, and later releases added native design tokens, so colours, spacing and typography can be managed as variables shared with code. Prototyping covers interactions, flows and overlays, and inspect mode shows CSS, SVG and code for each element. Migration from Figma is possible through an exporter plugin, although complex files may need cleanup afterwards. The hosted version is free with unlimited projects and collaborators, and the whole platform can be self-hosted under the MPL 2.0 license with Docker or Kubernetes.

Penpot fits teams that want to avoid per-seat design tool costs, organisations that must keep design data on their own servers, open-source projects and developer-heavy teams. Its plugin and template ecosystem is far smaller than Figma's, very large files can feel slower, and developer handoff and advanced prototyping are less mature. Figma remains the industry standard for agencies and client work, Sketch is a macOS-native option, and Framer suits designers who want to publish websites directly from their designs.
