Stream Chat vs. ZEGOCLOUD

Stream Chat is a messaging API and SDK suite for developers building in-app chat. Teams integrate it to ship production messaging in weeks instead of building and maintaining real-time infrastructure in-house. Client SDKs cover React, Swift, Android, Flutter, React Native, Angular, JavaScript, Unity, and Unreal, each with a UI kit you can customize or replace entirely. The backend runs on Go and RocksDB across 12 global edge locations, holding sub-40ms latency and 5M concurrent connections in a single channel behind a 99.999% uptime SLA.

Our journey in audio and video hardware and software development started back in 2001. The core team focused on key technologies in digital signals, algorithms for voice and video, as well as network transmission. We’ve learned from years of experience that delivering real-time audio and video is no easy feat. It can only be achieved with a wealth of knowledge in many different fields. Yet in this digital era, there are so many use cases for voice and video interaction to build bridges and forge links.
