Overview

Knock is notification infrastructure: one API and workflow builder for sending product notifications across email, push, SMS, and in-app feeds, with batching, preferences, and routing handled for you. The pitch is replacing the in-house notification service most teams eventually regret building. Product teams and developers who've outgrown scattered, hard-coded notification logic are the fit, especially those managing several channels and user preferences at once. Costs scale with volume, so heavy senders should model pricing carefully. Against building it yourself, Knock trades a recurring bill for not maintaining cross-channel delivery, preference centers, and digest logic. Against Courier it's a close comparison on developer-focused notification orchestration.
