Trigger.dev

About Trigger.dev

Trigger.dev is an open-source platform for writing long-running AI agents and background workflows in TypeScript and running them as fully managed infrastructure. The problem it exists to solve is the one every serverless deployment hits the moment an agent gets interesting: a task that needs to run for ten minutes, retry a flaky model call, fan out to a hundred sub-tasks and survive a redeploy does not fit a request-response timeout. Tasks are ordinary TypeScript functions with durable execution around them — retries, queues, concurrency limits and elastic scaling are configuration, not code you write. Scheduled tasks give durable cron without timeouts. Realtime connects a frontend directly to a running task so a UI can stream progress rather than poll. Observability and tracing are first-class, with custom dashboards, log retention and alert destinations tiered by plan. The team ships an official MCP server, which as of the current changelog carries agent chat, prompt management and reports, so the platform is drivable from a coding agent as well as from code. It is genuinely open source and self-hostable, with a documented self-hosting guide, and the cloud plans are a convenience layer over that rather than the only way to run it. Cal.com's booking engine is the reference deployment. The pricing model is credits plus concurrency, which maps cleanly onto how agent workloads actually consume resources.
