Open-source multiplayer canvas where humans and MCP agents design live HTML frames.
An infinite canvas where MCP agents sketch frames beside you. Tasks, comments, and taste live on the board so the next agent picks up mid-thought. Free in beta. Self-host with Docker if you want it off their servers.
