Doop

Open-source multiplayer design canvas where humans and AI agents design together.

Webfreeglobal

Doop is an open-source, self-hostable multiplayer design canvas where humans and AI agents design together live, positioned as an open alternative to Paper.design. Designs live as frames on a shared canvas, rendered as real HTML in sandboxed iframes, with MCP built in so AI agents can edit alongside people in the browser. It's built for designers and developers who want AI agents directly collaborating on visual design work.
