Drawgent: Coding agent on a live Excalidraw canvas
Open-source tool drawgent connects Claude Code, Codex, or opencode to a live Excalidraw canvas for diagram-driven coding tasks.
drawgent is a Rust-based tool that bridges locally installed Claude Code, Codex, or opencode agents to an Excalidraw whiteboard via ACP with MCP canvas tools. Users write 'AGENT:' notes on the canvas and the agent inspects screenshots plus the scene, edits drawings live, and marks notes as DONE. It supports attaching to running agent sessions, joining end-to-end-encrypted excalidraw.com collaborative rooms, and Docker-based hosting.
