About Knock

Knock is a commercial service that handles the notification layer of a product. Developers trigger an event through the API, and Knock runs a workflow that decides which messages to send, to whom, on which channel and when, instead of that logic being scattered across application code.

It supports channels such as email, SMS, push, chat tools and an in-app notification feed, with prebuilt feed components for front-end frameworks. End users can set their own preferences about what they receive and where, and the dashboard lets non-engineers edit templates and workflows. It suits product and engineering teams that want a maintainable notification system without building one from the ground up.
