Panel Reviews
The Builder
Developer Perspective
“One API for all notification channels. The workflow builder handles complex routing and preferences elegantly.”
The Skeptic
Reality Check
“Building notification infrastructure from scratch is surprisingly complex. Knock handles preferences, batching, and multi-channel delivery.”
The Futurist
Big Picture
“Notification infrastructure as a service will become standard. Every app needs it, nobody wants to build it.”
Community Sentiment
“Notification infrastructure is one of those things you don't want to build yourself — Knock gets it”
“Workflow builder for multi-channel notifications saved us weeks of backend work”
“Single API for in-app, email, SMS, and Slack — exactly what notification infra should be”
“Finally an abstraction that treats notifications as a product concern, not an afterthought”
