Reviewer scorecard
“Essential for dev teams. GitHub, CI, and alerting integrations make it the nervous system of any engineering org.”
“The most complete chat API with pre-built React, Flutter, and native components. Moderation and threads are production-ready.”
“It's bloated and expensive at scale, but there's no real alternative that matches its ecosystem. Reluctant ship.”
“Expensive but building chat infrastructure from scratch is more expensive. Stream handles the edge cases.”
“Canvas, clips, and huddles have made it more than just chat. Great for async creative collaboration.”
“In-app communication is essential for engagement. Stream's infrastructure removes the need to build this yourself.”
