What is Knock?
Knock is a notifications infrastructure platform that gives developers a complete system for sending and managing product notifications across every channel — email, push, SMS, in-app feeds, Slack and more — without building and maintaining that complex infrastructure themselves. Notifications seem simple until you actually build them: you need cross-channel delivery, user preferences, batching and throttling, templates, routing logic, and reliability, all of which add up to a substantial, ongoing engineering effort that distracts from core product work. Knock handles it as a service.
The platform lets teams design notification workflows — defining what triggers a notification, which channels it goes to, how it's batched or delayed, and how user preferences are respected — through a combination of a powerful API and a visual dashboard. It manages the messy realities like respecting quiet hours, consolidating multiple events into digests, handling per-user channel preferences, and ensuring reliable delivery, while providing the templates and localization features needed for polished, on-brand notifications. It also includes ready-made components for in-app notification feeds, so adding a notification center to your product is straightforward.
This makes Knock valuable for any product that needs to keep users informed and engaged through notifications — which is to say nearly all modern software. By centralizing notification logic in one system, teams avoid scattering notification code throughout their codebase and gain the ability to manage, observe and iterate on their messaging easily. It frees developers from reinventing notification infrastructure and gives product teams control over a critical part of the user experience. As notifications grow more important for engagement and span ever more channels, dedicated infrastructure to manage them well becomes increasingly worthwhile. For development teams that want robust, cross-channel, preference-aware notifications without building and maintaining the underlying system, Knock offers a comprehensive, developer-friendly and genuinely useful platform.
