Comet Lab Atlas

An open-source framework for long-running background jobs written as plain TypeScript code.

Trigger.dev lets developers write background jobs as normal TypeScript, with no timeouts and no separate queue to manage. Long-running tasks, retries, and concurrency are handled by the platform.

It is built for the AI use case in particular: jobs that call models, wait, and run for minutes are first-class rather than fought against.

Where it's ideally used

A strong fit for TypeScript teams running long AI jobs — model calls, pipelines — that outlast a normal serverless request.

Where it doesn't fit

A code-first, TypeScript-centric tool — not for no-code users or Python-only stacks.
