Penpot

Penpot is an open-source design platform for teams building digital products. It supports design and prototype work in the browser or on self-hosted infrastructure, giving teams ownership of their design environment and helping avoid vendor lock-in.

Designs use open standards including SVG, CSS, HTML, and JSON. Penpot includes real-time collaboration, inspect mode with SVG, CSS, and HTML code, responsive layout tools based on CSS Grid and Flex Layout, native design tokens, components, variants, plugins, webhooks, an API with access tokens, and an MCP server for design-code workflows.

Penpot can be used as SaaS or deployed on your own servers, including Docker, Kubernetes, Elestio, and other options. It is licensed under MPL-2.0 and is built with Clojure and ClojureScript.
