Hatchet is a task-orchestration engine that runs background tasks, AI agents, and durable workflows at scale. It uses Postgres as its backing store rather than a separate message broker, which keeps the self-hosted operational footprint small — one database instead of a queue plus a state store. The backend is written in Go, with SDKs for Python, TypeScript, Go, and Ruby.
It targets teams that have outgrown a plain job queue and need durability, retries, concurrency control, and observability over long-running or multi-step workflows — including agent runs — without adopting a heavier orchestration stack. MIT-licensed and self-hostable, with a managed cloud tier available.
