Trigger.dev

Trigger.dev is an open source platform for building AI workflows in TypeScript. It is built for long-running tasks that need retries, queues, observability, and elastic scaling without the limits of short-lived serverless jobs.

You write tasks in your codebase with a JavaScript and TypeScript SDK, then use durable tasks, cron schedules, waits, batch triggering, and structured inputs and outputs. It also adds human-in-the-loop waitpoints, realtime run updates and LLM streaming, logging and tracing, preview branches, and configurable machines.

Trigger.dev is licensed under Apache-2.0 and runs on the managed cloud service or self-hosted. Self-hosting uses Docker Compose to spin up an instance or an official Helm chart to deploy to a Kubernetes cluster, with support for DEV, STAGING, PREVIEW, and PROD environments.
