Trigger.dev solves a fundamental problem in modern TypeScript applications: running reliable background tasks without managing infrastructure. Unlike AWS Lambda or Vercel serverless functions that impose strict timeouts, Trigger.dev lets tasks run indefinitely with built-in checkpointing. When a task waits for an external callback or timer, the process is suspended and resumed later — you only pay for active compute time. The platform supports human-in-the-loop workflows, making it ideal for AI agents that need approval steps.
The developer experience is remarkably smooth: write tasks as standard async TypeScript functions in a /trigger folder, deploy via CLI, and monitor everything through a visual dashboard with full trace views. Trigger.dev integrates with any Node.js SDK and supports custom runtimes including Python scripts, FFmpeg, and headless browsers. The v4 release added MCP server support, making it a natural fit for building AI agent infrastructure with tool calling and orchestration.
Pricing is usage-based with a free cloud allowance, paid managed plans, and self-hosting options documented for Docker and Kubernetes. With 15,000+ GitHub stars, Apache 2.0 license, and backing from Y Combinator, Trigger.dev has become a go-to TypeScript background jobs and AI workflow platform — teams like flick.social reported going from 87% to 100% task success rates after migrating from Temporal.
