Cinny is an open-source, web-based Matrix chat client offering an intuitive Discord-style interface with end-to-end encryption and total data custody.
Ajay Bura launched Cinny in 2021 as a web client for the Matrix protocol to give users an organized, familiar chat interface without the visual clutter of existing decentralized tools. By packaging Matrix into a static single-page application that connects to any standard homeserver, it allows organizations to run real-time messaging on their own infrastructure. That origin gives small teams and technical leads a Discord-like communication layer with complete custody over data, keys, and message archives.
Discord operates as a centralized commercial silo where user communications, attachments, and identity records reside on corporate servers. For agencies and operations teams managing proprietary client assets or private infrastructure communications, hosting discussions on a third-party platform introduces regulatory exposure and vendor lock-in. Cinny replaces that dependency by functioning as a client for the open Matrix federation protocol. When paired with a self-hosted homeserver such as Synapse or Conduit, databases and cryptographic credentials stay under internal control, protected by Matrix's Olm and Megolm end-to-end encryption standards.
The operational trade-off centers on platform breadth versus governance. Discord provides zero-configuration setup, ubiquitous mobile apps, and low-latency voice channels with screen sharing. Cinny focuses on structured text communication, spaces, and direct messaging, handling audio and video through basic WebRTC calls. While running Cinny requires selecting or managing a Matrix homeserver, teams eliminate third-party tracking, prevent unexpected account suspensions, and protect confidential discussions from commercial data harvesting.
Can Cinny connect to any Matrix homeserver? Yes, Cinny can connect to any homeserver supporting the standard client-server Matrix API, including private Synapse instances and public servers like matrix.org.
Cinny vs Discord — which should a privacy-conscious team choose? Cinny is the better choice for teams requiring full data ownership and end-to-end encryption, while Discord suits communities prioritizing built-in voice lounges and zero-ops hosting.
Is Cinny free for commercial use? Yes, Cinny is completely open source and free to deploy internally across commercial teams without seat limits or recurring software fees.
Cinny is the right choice for teams seeking Discord's familiar channel layout alongside the data sovereignty and encryption of the Matrix protocol. It is not suitable for organizations that depend on native mobile apps or persistent voice channels, but active maintenance through September 2026 and an AGPL-3.0 license make it a dependable frontend for self-hosted team communication.
