SAMA

SAMA is an open-source messaging server designed as a modern alternative to legacy chat protocols. It provides real-time WebSocket and HTTP APIs for users, conversations, messages, activities and address books, and ships with reference web and mobile clients.

Key Features

• High-performance WebSocket core powered by uWebSockets.js for low-latency messaging
• REST and real-time APIs covering Users, Conversations, Messages, Activities, Address Book and Push Notifications
• Persistent storage using MongoDB and ephemeral/state features backed by Redis (presence, caching/pubsub)
• End-to-end encryption support and built-in push notification flows
• Clustering and horizontal scaling primitives for multi-node deployments
• Docker-friendly deployment and reference frontend (web) and Flutter mobile clients
• GPL-3.0 licensed project with an emphasis on a compact, modern protocol alternative to XMPP

Use Cases

• Add real-time chat, group conversations and activity streams to mobile and web applications
• Build team chat or community messaging platforms with end-to-end encryption and push notifications
• Implement lightweight, scalable messaging backends for consumer or enterprise apps requiring low latency

Limitations and Considerations

• Uses a custom SAMA protocol (designed as an alternative to XMPP) which has a smaller ecosystem and fewer third-party clients
• GPL-3.0 license can restrict embedding into proprietary products without complying with license terms
• High-concurrency deployments require tuning and appropriate resources for uWebSockets.js, MongoDB and Redis

SAMA is a focused chat server for teams and apps that need a high-performance, modern messaging backend. It is suitable for projects that can adopt its protocol and license model and want a Docker-friendly, scalable real-time messaging stack.
