MongooseIM

MongooseIM is an open-source XMPP server designed for large scale instant messaging installations. It functions as a backend platform that supports clustering across multiple machines or virtual machines to ensure fault tolerance and scalability. The server manages the routing and delivery of messages within a network, providing the core infrastructure necessary for real-time communication at scale.

The software is deployed as a server and can be installed via Docker images, Helm charts, or pre-built packages for Ubuntu, Debian, CentOS, AlmaLinux, and Rocky Linux. It handles client sessions through various connection methods to accommodate different network requirements, allowing it to serve as the foundation for a wide range of messaging applications and team chat environments.

Key features

• Support for vanilla XMPP, REST API, and SSE connection methods
• Integration of Websockets and BOSH HTTP long-polling
• Clustering capabilities to distribute load across multiple nodes
• GraphQL API for both user and administrative management
• Built-in test suite and load testing platform
• Integrated metrics and a dedicated monitoring server
• Support for multiple database backends
• Compatibility with various XEPs and RFCs

Built using Erlang, the platform is designed for enterprise environments that require high availability and efficient resource utilization. It provides a comprehensive server developer guide for extending the platform with new modules and custom functionality. The architecture allows administrators to manage nodes through a specific Admin API, while developers can build client applications using a dedicated User API. To ensure stability in production, the platform includes tools for monitoring and operation maintenance, which help administrators track the health of the cluster.

MongooseIM is positioned as a scalable infrastructure component for organizations deploying large scale encrypted communication and messaging services.
