Whiteboard gives coding agents an architecture canvas

Whiteboard, /dev/fast’s open-source desktop canvas for software design, reached 1,524 GitHub stars after its v0.1.3 release landed on September 26. The MIT-licensed project lets coding agents draw sequence and database diagrams, expose semantic diffs, and replay agent trajectories; its v0.1.3 release adds Windows builds alongside macOS and Linux packages. Builders experimenting with autonomous coding should file this as a review-layer signal: agent output is getting a visual architecture checkpoint, not just a green test suite; adoption, not another model benchmark, will show whether that control surface sticks. See the archive’s case for switching coding workflows for why this layer matters.
