Trigger.dev is a platform for building durable, event-driven background workflows. It functions as a workflow engine that allows developers to define complex, long-running processes using standard code rather than proprietary configuration languages. By utilizing a durable execution model, the system checkpoints progress, ensuring that tasks can automatically resume from the exact point of failure after a crash or interruption.
The platform distinguishes itself through its focus on stateful, multi-step automation and real-time feedback. It supports the orchestration of AI agents and external tools, enabling the creation of persistent agents that can handle complex logic, including human-in-the-loop approval steps. To maintain transparency, the system provides real-time observability by streaming execution logs and progress updates directly to user interfaces, allowing for immediate monitoring of background processes.
Beyond core orchestration, the platform manages the infrastructure required to run these tasks reliably. It provides containerized isolation for each workflow, ensuring consistent dependency management and resource separation. The system also includes built-in capabilities for distributed task queueing, concurrency control, and scheduled job management, alongside automated deployment pipelines that integrate with version control systems.
