Notification infrastructure for product teams
Knock is a notifications platform that lets you orchestrate multi-channel notifications (email, SMS, push, in-app, Slack) from a single API. Define notification workflows in a visual editor, manage user preferences, handle delivery windows and batching, and get full observability into delivery. Designed to replace ad-hoc notification logic scattered across codebases.

Trigger.dev is an open-source platform for creating and running background jobs, scheduled tasks, and event-driven workflows in TypeScript. It runs alongside your existing codebase with zero infrastructure — jobs run as durable functions with automatic retries, real-time observability, and fan-out support. Designed for long-running tasks in serverless environments.
Trigger workflows with knock.workflows.trigger({ key, recipients, data }). Recipients must be identified first with knock.users.identify(). Workflow keys are defined in the Knock dashboard. For in-app feeds, use the @knocklabs/react SDK on the client. Prefer server-side triggers from API routes or background jobs.
