c0va23/centrifugo repository overview

Centrifugo is a real-time messaging server. It's language-agnostic and can be used in conjunction with application backend written in any language - Python, Ruby, Perl, PHP, Javascript, Java, Objective-C etc.

Centrifugo runs as separate service and keeps persistent Websocket or SockJS connections from your application clients (from web⁠ browsers or other environments like iOS⁠ or Android⁠ apps). When some event happens you can broadcast it to all interested clients using Centrifugo API.

Read documentation⁠ to get details. You can also find this introduction post⁠ interesting – this is a story behind Centrifugo.

Releases available as single executable files – just download latest release⁠ for your platform, unpack and run.

See official Docker image⁠.

There are also packages for 64-bit Debian, Centos and Ubuntu⁠.

Try demo instance⁠ on Heroku (password demo). Or deploy your own Centrifugo instance in one click:
