Hatchet
The orchestration engine for teams who ship
Hatchet is a platform for orchestrating AI agents, background tasks and mission-critical workflows written as code in TypeScript, Python or Go. It handles retries, dependencies, scheduling, cron and event triggers, and stores the history of every task for debugging and replay. Workers run on your infrastructure with the engine managed or self-hosted; the project is MIT-licensed open source.
