Stream Chat vs. Webex Connect

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.

Webex Connect is an enterprise Communications Platform as a Service (CPaaS) that enables rapid automation of multi-channel customer journeys. The platform makes it easy for businesses to interact with their customers anywhere in the world on any channel -- SMS, Voice, RCS, Push, In-app, Email, Apple Business Chat, Facebook Messenger, WhatsApp, and other messaging apps, Webex Connect automates orchestration of these interactions with backend systems. A visual drag-&-drop builder allows you to build and launch flows that work across channels and systems.
