Doop

Doop is an open-source multiplayer design canvas and MCP server for AI agents.

Doop is an open-source multiplayer design canvas and design MCP server that enables users to design side by side with AI agents like Claude Code and Codex. Agents join the canvas via OAuth to sketch frames, fill real copy, and review their own work using a built-in headless renderer. Users can paste URLs to import editable snapshots, queue tasks for six specialized agent roles, and leave feedback that the system distills into a persistent taste profile. Every frame functions as a live-updating URL, and tasks, decisions, and comments are stored in a shared canvas memory. The product supports image generation with models such as GPT Image 2 and runs as a single Docker container with Postgres.
