What it is

A Matrix chat client built as a web app, with a desktop build in a companion repository. It focuses on an uncluttered interface for rooms, direct messages and spaces, with end-to-end encryption support. People who want a lighter-feeling Matrix client use the hosted version at app.cinny.in or serve the static files or Docker image on their own web server, pointing it at their preferred homeservers.
