SAMA

Open-source, end-to-end encrypted chat server with clustering support.

PlatformWebfreeglobal

An open-source chat server that provides end-to-end encryption and built-in clustering to support horizontally scalable mobile and web apps. It includes common backend features—private and group messaging, typing indicators, read receipts, file attachments, authentication and profile editing, user search and blocking, multi-device sync, presence, push notifications, and an admin frontend—so teams can avoid building encrypted, clustered chat infrastructure from scratch. Intended for developers who need a self-hosted backend for custom chat-enabled apps rather than a consumer chat client.
