What is it like to partner with the MongooseIM team?

Reliable Instant Messaging Solution
No Matter How Many Users You Have

MongooseIM is built in Erlang, meaning scalability comes as standard. Your instant messaging server will be able to handle spikes and loads with ease allowing you to have millions of concurrent users without a problem. 


MongooseIM makes use of the proven and extensible XMPP protocol. And, it’s an open source product. This gives users the freedom to add their own XEP extensions to suit their needs, without any help from us. MongooseIM also offers customers a chat solution with the flexibility to choose the features they require without being locked into ongoing usage contracts.


MongooseIM makes use of the REST API and TOML configuration to allow accessibility to as wide a range of developers as possible. You don’t need to be an Erlang or XMPP expert to manage your MongooseIM deployment.
