Whiteboard is a canvas for thoughtful software development. Critique interactive visualizations, diffs, and agent trajectories, all from one interface.
Whiteboard is an open-source desktop app where humans and agents architect software together on a shared canvas. It’s the easiest way to ship fast with coding agents while still understanding your codebase.
We made Whiteboard because coding with agents was exhausting: we were constantly switching between the terminal, our IDEs, and HTML visualizations to give feedback on the walls of text we were squinting at all day.
Whiteboard plugs into the tools you already use - Claude Code, Codex, etc. - and gives your agent an SDK to draw on a persistent, in-app canvas. The app is designed to capture the feeling of a productive whiteboard session with another engineer.
When you click on any visualization – like a sequence diagram, an entity relationship diagram, or a quote from the agent’s trace – you jump directly to the underlying code. When navigating code, you get keybindings and LSP support from VSCode out of the box.
Folks at companies like Salesforce, Modal, and Nvidia are using Whiteboard today to iterate on prototypes with their coding agents. They’re also pulling intimidating PRs into the app to make sense of them.
Clicking a sequence diagram and landing in the underlying code is exactly what's missing when reviewing agent PRs. Do the canvas drawings stay in sync when the code changes later, or are they snapshots of that session?
