Reviewer scorecard
“One API for all notification channels. The workflow builder handles complex routing and preferences elegantly.”
“The open protocol for secure communication. Self-hosting and bridging to Slack/Discord/Telegram is powerful.”
“Building notification infrastructure from scratch is surprisingly complex. Knock handles preferences, batching, and multi-channel delivery.”
“UX is still rough compared to Slack or Discord. The decentralization benefits don't outweigh the polish gap for most teams.”
“Notification infrastructure as a service will become standard. Every app needs it, nobody wants to build it.”
“Decentralized, end-to-end encrypted communication is the right architecture. Matrix is building the open alternative.”
