ejabberd is a distributed, fault-tolerant technology that allows the creation of large-scale instant messaging applications.
The server can reliably support thousands of simultaneous users on a single node and has been designed to provide exceptional standards of fault tolerance.
ejabberd is free and open source software.
Features include:
- Distributed – un ejabberd on a cluster of machines and all of them will serve the same XMPP domain(s).
- Fault-tolerant – deploy an ejabberd cluster so that all the information required for a properly working service will be replicated permanently on all nodes. This means that if one of the nodes crashes, the others will continue working without disruption. In addition, nodes also can be added or replaced ‘on the fly’.
- Modularity – load only the modules you want.

- SASL and STARTTLS for c2s and s2s connections.
