Trigger.Dev

Trigger.dev is a TypeScript framework for building and running long-running background jobs and workflows that do not fit the request-response model of traditional serverless functions. Where a typical serverless function times out after seconds or minutes, Trigger.dev jobs can run for hours, days, or indefinitely — with built-in durability, automatic retries, queueing, and observability. The framework is designed for the AI-agent era: agentic workloads (multi-step LLM pipelines, human-in-the-loop approvals, long-running data processing) are a poor fit for conventional job runners, and Trigger.dev targets that gap directly. Developers define tasks in plain TypeScript, deploy them, and the platform handles execution, state persistence, and monitoring. Additional capabilities include streaming support for realtime apps, human-in-the-loop checkpoints where a job pauses for external input, and integration with common AI SDKs. The project is open-source (over 15,000 stars) and can be self-hosted, with a managed cloud edition for teams that do not want to operate the runtime. It sits alongside tools like Inngest and Temporal in the durable-execution category; its differentiator is the TypeScript-first developer experience and the explicit focus on AI workloads rather than general-purpose orchestration.
