Reviewer scorecard
“One API for all notification channels. The workflow builder handles complex routing and preferences elegantly.”
“The most complete chat API with pre-built React, Flutter, and native components. Moderation and threads are production-ready.”
“Building notification infrastructure from scratch is surprisingly complex. Knock handles preferences, batching, and multi-channel delivery.”
“Expensive but building chat infrastructure from scratch is more expensive. Stream handles the edge cases.”
“Notification infrastructure as a service will become standard. Every app needs it, nobody wants to build it.”
“In-app communication is essential for engagement. Stream's infrastructure removes the need to build this yourself.”
