Panel Reviews

The Builder

Developer Perspective

Ship

“One API for all notification channels. The workflow builder handles complex routing and preferences elegantly.”

The Skeptic

Reality Check

Ship

“Building notification infrastructure from scratch is surprisingly complex. Knock handles preferences, batching, and multi-channel delivery.”

The Futurist

Big Picture

Ship

“Notification infrastructure as a service will become standard. Every app needs it, nobody wants to build it.”
