ejabberd is an open-source, massively scalable real-time messaging platform written in Erlang/OTP that combines an XMPP server, MQTT broker, and SIP service in a single process. It has been maintained since 2002 and powers large deployments at WhatsApp, Nintendo, BBC, and Facebook, supporting millions of concurrent users per node.

Use cases

self-host an XMPP chat server for my organization
run an MQTT broker for IoT device telemetry
deploy a federated instant messaging server
host group chat and MUC rooms at scale
add voice and video calling via SIP and WebRTC
build a messaging backend for multiplayer games
support millions of concurrent messaging users

When to choose

you need a battle-tested, massively scalable XMPP server with federation
you want XMPP, MQTT, and SIP in one unified platform
you need self-hosted messaging with strong protocol compliance (400+ XEPs)
you require clustering and fault tolerance via Erlang/OTP

When to avoid

you only need a simple chat app backend without XMPP/MQTT protocols
your team cannot operate an Erlang-based server or its configuration model
you need a lightweight single-protocol broker with minimal resource usage
