Trigger.dev

London-based Trigger.dev provides infrastructure for building and running production AI agents and automated workflows, with the observability, retries and scaling that real systems need.

Its open-source roots and TypeScript SDK have earned it a sizeable developer following. As teams move agents from demos into production, the unglamorous problems of reliability and monitoring become critical - exactly what Trigger.dev addresses.

It is part of the emerging tooling layer for the agent era.
