Overview
Trigger.dev is an open source platform for building and deploying fully-managed AI agents and workflows in TypeScript. It lets developers write long-running, durable tasks that survive refreshes, redeploys, and crashes, while offloading execution to managed infrastructure that handles scaling, retries, and observability.
Developers love Trigger.dev because it removes the pain of managing timeouts, queues, and background jobs. You write simple, reliable code in your Trigger folder, and the platform takes care of deployment, concurrency, and real-time status updates. It supports a wide range of AI patterns including autonomous agents, prompt chaining, routing, parallelization, orchestrators, and evaluator-optimizers.
With built-in human-in-the-loop approval, streaming to your frontend without API routes, and full observability, Trigger.dev makes it easy to build production-grade AI applications that scale to any size.
Key Features
- Durable AI Agents: Build agents that survive refreshes, redeploys, and crashes with automatic retries and state persistence.
- No Timeouts: Write simple, reliable code and never hit a timeout — tasks run as long as they need to.
- Human-in-the-Loop: Pause execution for human approval on sensitive actions while keeping the run alive.
- Real-time Streaming: Stream responses directly to your frontend with no API routes required.
- Elastic Scaling: Pay only when your code is actually executing, with no servers to manage.
- Advanced Observability: Alerts via email, Slack, or webhooks, advanced filtering, and atomic versioning for safe deployments.
Use Cases
- AI Product Teams: Build and deploy autonomous AI agents with tool calling, human approval, and full observability for customer-facing applications.
- Backend Engineers: Offload long-running async tasks like media processing, browser automation, and scheduled jobs to managed infrastructure.
- Data & ML Teams: Orchestrate complex multi-stage AI workflows with rer
