What is Knock?
Knock helps businesses engage users at every step of their journey, from transactional to lifecycle messaging across in-app and out-of-app channels.
Ship messaging without limits. Developer-first tooling allows you to build any messaging experience you want, without compromising on design, performance, or user experience. Ship in-app messaging using your own components, and enable non-engineers to edit copy and targeting in Knock.
Unify and activate your data. Ingest real-time data from your product and warehouse so you can trigger relevant, timely messaging based on any user attribute, event, or action.
Built by developers, for developers. Knock is flexible, reliable messaging infrastructure that's built to scale with you. Use our APIs to engage users, power cross-channel workflows, and manage notification preferences. Bring Knock to your development workflow with environments, version control, and the Knock CLI.
