Doop

About Doop

Doop is an open-source, multiplayer design canvas. Each canvas holds frames that render real HTML, so designs are close to production code. People edit in the browser or desktop app, while AI agents such as Claude Code connect through the built-in MCP server and stream their designs onto the canvas live, with shared cursors, presence and an activity feed. It also has pages, layers, sharing and imports. The Personal plan is free; self-hosting under AGPL-3.0 has billing switched off, so every feature is unlocked. The paid hosted Team plan only adds shared workspaces with roles. The built-in AI agent includes a few free tasks, then needs your own ChatGPT/OpenAI account; connecting your own agent stays free.
