The GitCMS Chrome extension has been sunset. It worked by injecting UI into GitHub's web interface, which meant every DOM change on GitHub's side could break it without warning. That dependency made it fragile and impossible to maintain reliably.
It also couldn't support agentic workflows — AI tools like ChatGPT and Claude had no way to interact with a browser extension.

ChatGPT, Claude, and other AI tools can draft and edit content in your repo through the Model Context Protocol. Review everything in the visual editor before it ships.
