Features

Simple deployment without any third-party dependencies, can be started with a single command.
Self-developed message database for permanent message storage.
Self-developed binary protocol with support for custom protocols.
End-to-end encryption of message channels and content to prevent man-in-the-middle attacks and message tampering.
Support for multiple device logins with real-time data synchronization.
Easy to use with powerful performance. In single-machine testing on a Mac notebook, it achieves a throughput of over 160,000 messages per second (including storage). To achieve this performance and ease of use, the system implements message storage completely independently, without relying on any third-party components.
Strong scalability using a channel-based design approach. Currently supports group channels and point-to-point channels, and can be extended to include custom channels for functionalities such as robot channels and customer service channels.
Supports both TCP and WebSocket protocols.
Channels support thousands of subscribers.
