Hatchet

Hatchet replaces traditional task queues like Celery or BullMQ with a durable, observable orchestration engine. Tasks and workflows are defined in code and executed by workers you run; Hatchet handles queueing, retries, timeouts, scheduling and DAG dependencies, and persists everything in PostgreSQL. It offers fairness and concurrency controls (per-key concurrency, rate limits, priorities), event triggers, cron schedules, durable sleep and wait-for-event, plus a real-time dashboard for monitoring runs. Hatchet can be self-hosted or used through Hatchet Cloud.
