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.
Features include threads, reactions, typing indicators, read receipts, push notifications, message search, translation, AI moderation, and role-based permissions. SOC 2, ISO 27001, GDPR, and HIPAA compliant.
Used by 4,000+ companies including Strava, Patreon, and Nextdoor, serving over 1 billion end users.
