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.

Third-party open-source projects. We are not affiliated with their authors; repositories are provided as-is by their maintainers. Review each project's license, code and security before installing. See our Disclaimer.

Pros: what Whiteboard does well

  • Agents explain changes visually
  • Semantic, AST-aware diff viewer
  • Free and open source

Cons: where it falls short

  • Files cannot be edited inside the app yet
  • Anonymous telemetry is on until you turn it off

Who Whiteboard is for

Developers who want to review and plan AI-written code with diagrams instead of long diffs.

Who can skip it

People who rarely use AI coding agents or review large changes.
