Get to know MongooseIM
MongooseIM is a robust, scalable and efficient XMPP server at the core of an Instant Messaging platform aimed at large installations.

Designed for enterprise, it is fault-tolerant, can utilise the resources of multiple clustered machines, and easily scales for more capacity by simply adding a box or a VM.
MongooseIM can accept client sessions over vanilla XMPP, REST API and SSE, as well as Websockets, and BOSH (HTTP long-polling).
As a platform, MongooseIM includes several server-side (backend) and client-side (frontend) components.
We provide a test suite, metrics, a load testing platform, and a monitoring server. We recommend third-party, open source client libraries for XMPP and REST API.
It is brought to you by Erlang Solutions.
