## The Hook

Whiteboard is a desktop OSS canvas where humans and coding agents share drawings, specs, and a decision trail wired into agents like Claude Code and Codex.

## What's Good

MIT (devdotfast/whiteboard). macOS/Linux downloads, agent SDK to draw on the in-app canvas, jump from diagrams to code, semantic/AST-aware diff viewer. Self-hostable OSS stance for the desktop app; site at dev.fast.

## The Catch

Vs Excalidraw: this is a human+agent design/decision workspace wired to coding agents, not a general hand-drawn whiteboard. Extreme overnight star fill (~589) is discovery noise; a hosted team product is planned — keep the self-hostable OSS desktop as the free bar until that SKU is real.

## Verdict

MIT human+agent canvas when specs and decisions need to live beside the coding agent — not another Excalidraw clone.
