why i built it
I wanted my agents to design in something I could see and change. Each frame is one HTML file, so an agent draws with the tools it already has, and the board shows the frame the moment the file lands.
how i use it
I use it every day to sketch interfaces and design systems and to work out UI fixes before they become code. I move, restyle and retype a frame by hand, or pin a note the agent answers in its thread. A Claude Code plugin checks each frame after the agent writes it, so a broken rule shows on the frame.
what it shows
I built it with canon, starting in October 2026. Open source on npm under the MIT license, with unit, end-to-end and macOS tests in CI.
