Stream Chat

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.
