Drawgent Review: Putting a Coding Agent on a Live Excalidraw Canvas (2026)
Drawgent is a local server that connects your own coding agent — Claude Code, Codex, or opencode — to a live, persistent Excalidraw canvas that you and the agent edit together. It ships no agent and no API key. It drives the agent you already have installed, in the repository you already have open.
