What is ejabberd?
ejabberd serves as a comprehensive real-time platform supporting multiple protocols, including XMPP for messaging, MQTT for IoT applications, and SIP for voice services. It operates as a cluster out of the box, ensuring high availability and fault tolerance with no message loss, even during mobile network disconnections. The platform is built on Erlang, enabling massive concurrency with support for up to 2,000,000 users on a single node and efficient cluster management through consistent hashing.
Customization is facilitated through a powerful API and modular architecture, allowing developers to extend functionality with plugins and hooks. It includes tools like ejabberdctl for command-line control, REST API for backend integration, and libraries for iOS, Android, and web clients with WebSocket support. Security features incorporate SSL/TLS encryption best practices, and the platform is professionally maintained with a global community, adhering to open-source principles under the GPLv2 license.
