penpot/penpot — reverse-engineered prompt

Build me an open source design and prototyping platform for product teams, similar to a browser based workspace where designers and developers can work together in real time.

Users should be able to create teams, projects, design files, pages, frames, shapes, text, reusable components, variants, and shared design tokens for colors, spacing, typography, and other design system values. The canvas should support responsive layouts using grid and flex style behavior, so designs feel close to real web interfaces. Add collaboration basics like comments, multiplayer editing presence, file sharing, and permissions.

Developers should have an inspect mode where they can click elements and see useful SVG, CSS, and HTML output. Designs should be saved in open formats as much as possible, and the app should support importing or exporting assets. Please include a way to self host it, plus an API, webhooks, and a plugin style extension system so teams can automate workflows later.

Look up current docs online if you need to.
