Hatchet is an open-source distributed task queue and workflow orchestration engine for background jobs, AI agents, and durable workflows. It is Postgres-backed, MIT-licensed, and ships with first-class SDKs for Python, TypeScript, Go, and Ruby plus a managed offering (Hatchet Cloud) and a self-hostable engine (Docker Compose, Hatchet Lite, Helm chart). The platform separates the orchestration engine from worker execution so workers can run on the operator's own infrastructure (Kubernetes, ECS, Render, Railway, Porter, or any container platform).
