Stream Chat vs. Messangi

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.

Messangi is a unified multichannel engagement platform designed to help enterprises, independent software vendors (ISVs), and business process outsourcing (BPO) companies connect their operational systems to the communication channels their customers prefer, including SMS, WhatsApp, RCS, Email, and Voice. This platform goes beyond traditional messaging solutions by treating communication as an integral part of business workflows rather than just a series of disconnected interactions.
