README

**Doop is the open-source alternative to [Paper.design](https://paper.design) — a multiplayer design canvas for humans _and_ AI agents.** Every design lives on a shareable **Canvas** (`/c/`) holding **Frames** — artboards that render real HTML in sandboxed iframes. People edit in the browser; AI agents edit through the built-in **MCP server**, streaming their designs in live. Everyone sees everything as it happens: cursors, presence, frame edits, agent status, and an activity feed.

Design with agents, not prompts-and-refresh — connect Claude Code (or any MCP client) once, then watch it sketch, stream and self-review designs on your canvas, next to your cursor.
A built-in Doop Agent — queue a card or @mention a role and it designs on its own, no client to connect. Runs on the server's ANTHROPIC_API_KEY for a handful of free tasks, then on the ChatGPT subscription (or OpenAI key) each user connects (setup); the first-canvas welcome performance is scripted and runs without any of it.
True multiplayer — live cursors, presence, per-f
