Whiteboard

Meet Whiteboard

Whiteboard is an open-source desktop app for understanding software changes at the level of their architecture and behavior. It combines code review with diagrams, semantic diffs, and explanations that can be expanded into the underlying source. A coding agent can illustrate a flow or a set of changes, while a developer follows the relationships and checks the implementation. The app also helps inspect agent trajectories to understand how decisions led to the resulting code. Whiteboard is available in public beta for macOS, Windows, and Linux under the MIT license, with a workflow centered on local development and review.
