Macaroni – a single HTML file messenger

Macaroni Messenger is a messaging application built as a single HTML file that stores conversations in git repositories instead of a traditional backend, supporting GitHub, GitLab, Gitea, and other git hosts. Users can connect their own repositories through browser adapters and send messages that are committed as JSON files in the repository's `.macaroni/` directory, with no signup, token management on the server, or real-time synchronization required. The project acknowledges limitations including lack of privacy for public repositories, dependency on browser capabilities, and polling-based message delivery rather than live updates.
