Cranban is a local-first kanban board that stores data in a markdown file. It syncs updates in real time to the local file, and syncs changes from the local file to the UI. The markdown file is human readable, and the UI is rendered in a browser, but works offline.

Cranban was used to build itself using Claude code, and the history can be seen in the cranban.md file in the GitHub repo. It is a great tool for collaborating with robots because the UI is designed for humans to use, and the markdown file is designed to be read and updated by coding agents.
