TypeScript workflows that survive serverless timeouts

What it does

Trigger.dev is an open-source platform for running background tasks and AI workflows in TypeScript. You write tasks in your codebase using an SDK, and the platform handles queuing, retries, concurrency limits, and observability. Deploy to its managed cloud or self-host with Docker Compose or Kubernetes.

The interesting bit

Unlike conventional serverless platforms, Trigger.dev imposes no execution timeouts and checkpoints task state automatically, so a workflow can pause for human approval, sleep for months, or survive a container restart without losing its place. It also lets you bundle non-JS dependencies—browsers, FFmpeg, Python scripts—into the same deployment.

Key highlights

• Durable execution with automatic checkpointing and no timeout ceiling
• Human-in-the-loop waitpoints for approval or feedback
• Real-time run streaming and React hooks for frontend integration
• Atomic versioning that deploys without disrupting in-flight tasks
• Optional self-hosting via Docker or Kubernetes Helm charts

Verdict

Worth exploring if you build AI agents or background workflows in TypeScript and need execution that outlasts typical serverless limits. Less compelling if your workloads are short-lived and already handled by a simple queue.
