Cinny is an open-source Matrix chat client with a simple, elegant interface for encrypted direct messages and group conversations. It signs in to any Matrix homeserver account, organizes rooms into Spaces, and ships as a free hosted web app, self-hosted static files or Docker image, and desktop builds for Windows, macOS, and Linux.[1][2]
Quick verdict
Cinny fits individuals and communities who chat over Matrix and want a lightweight, elegant client. It connects to any homeserver with encrypted messages and rooms, Spaces, calls, and desktop apps. It provides no accounts or hosting itself, and published support covers web and desktop only. If you hold a homeserver account, start with the free hosted web app; if you need native mobile apps or a managed host, compare alternatives first.[1][2][3]
Key features
Any-homeserver Matrix messaging Cinny connects to any Matrix homeserver, so one client handles federated direct messages and group rooms across the Matrix network.[1]
End-to-end encrypted chats Direct messages and group conversations use end-to-end encryption through the Matrix protocol, keeping content private between participants.[1][2]
Voice and video calls Built-in voice and video calling covers real-time conversation alongside text messaging.[1]
Spaces for communities Spaces group rooms into communities, so large sets of rooms stay organized instead of one flat list.[1]
DMs kept separate from rooms An L-shaped layout keeps direct messages apart from group rooms, matching how people actually separate personal and group chat.[1][2]
Themes, stickers, and emoji Custom themes, stickers, and emojis let people and communities shape the look and tone of their chat.[1]
Desktop apps for three platforms Native-feeling desktop builds ship for Windows, macOS, and Linux alongside the hosted web app, which updates with each release.[1][2]
Static-file and Docker self-hosting Self-hosting means serving the release tarball as static files or pulling the Docker image, with default homeservers and explore pages set in a small JSON config.[1]
Who will love it
Individuals and communities chatting over Matrix who want a lightweight client with a clean, modern interface.[1][2]
Teams running their own Matrix homeserver that need a simple client for members, with defaults preset through the JSON config.[1]
Desktop-first users on Windows, macOS, or Linux who want a native-feeling app rather than a browser tab.[1][2]
Who should avoid it
Cinny provides no accounts or hosting itself; everyone needs a Matrix homeserver account to sign in to.[1][2]
Published platform support covers the web app and desktop builds only, so phones use the web app rather than a native mobile client.[1]
Self-hosting needs real web-server work: redirect rules for clean URLs unless hash routing is enabled, and a rebuild to deploy under a subdirectory.[1]
Compatibility and hosting
Works with any homeserver Any Matrix account works, and self-hosters can preset default homeservers and explore pages in the JSON config.[1][2]
Hosts anywhere static files run The client is static files or a Docker image, so it deploys on any web server or container host with small resource needs.[1]
Questions worth asking
What is the best Cinny alternative for non-technical users?
For non-technical users the simplest path is the free hosted web app at app.cinny.in with an account on a public homeserver; self-hosting is the path for people comfortable configuring a web server. Switching Matrix clients later keeps the same account, because the account lives on the homeserver, not in Cinny.[1]
Is Cinny really no-code?
How much does Cinny cost per month?
Can you self-host Cinny?
Yes. Download the release tarball and serve the static files from any web server, or pull the Docker image from DockerHub or GitHub Container Registry, with defaults set in a small JSON config. Subdirectory deploys need a rebuild, and servers need redirect rules unless hash routing is enabled.[1]
