What is Whiteboard?
Whiteboard is a free, open-source desktop app from dev.fast where people and AI coding agents architect software in one shared workspace. Connect Claude Code, Codex or another agent and it draws diagrams, semantic diffs and decision logs on a canvas, so you can review a branch visually instead of scrolling raw diffs.
