social.plus vs. Stream Chat

social.plus is the leading engagement infrastructure for consumer apps. We offer pre-built components that make it easy to add social and interactive experiences to any app without building from scratch, helping turn episodic usage into daily engagement and stronger retention. Every interaction generates valuable first-party data and insights that translate into measurable business outcomes across the customer lifecycle.

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.
