Trigger.dev

Trigger.dev is an open source platform for building and running durable AI agents and background workflows in TypeScript. Developers write tasks as ordinary functions in a trigger folder in their codebase, and the platform deploys them to managed workers that have no timeouts, retry on failure, queue work and scale with demand. Runs survive page refreshes, redeploys and crashes, which makes it suited to long running AI jobs that would break in a normal serverless function. It is aimed at engineering teams shipping AI features, media processing and generation, browser automation, scheduled jobs and email sequences. Agent support covers tool calling, human in the loop approval that pauses a run until someone responds, streaming responses straight to the frontend without extra API routes, and patterns such as prompt chaining, routing, parallelization and orchestration. Observability includes run logs, custom dashboards, LLM telemetry and alerts to email or Slack. The whole platform can also be self hosted from the published guide. Cloud pricing is published.
