Cinny

Cinny is an open-source Matrix client that focuses on delivering a simple, elegant, and secure instant messaging experience built on decentralized communication technology. As a web-based Matrix client, Cinny emphasizes a modern and streamlined interface, clean navigation between direct messages and channels, and a design that prioritizes clarity and ease of use while preserving strong security through end-to-end encryption. Users can self-host Cinny, deploy it via Docker or as a static web app, and connect to Matrix homeservers to participate in federated chats across communities and personal networks. The client also supports common Matrix features such as spaces, multi-account login, threads, and secure messaging patterns that make it competitive with other decentralized IM platforms.
