Hatchet

Hatchet is a modern, open-source background task queue and workflow engine that helps developers run reliable, distributed background jobs and orchestrate complex workflows at scale. Almost every serious application needs to do work outside the request-response cycle — sending emails, processing data, calling external services, running AI tasks, handling long-running operations — and doing this reliably is harder than it looks. Hatchet provides a robust, developer-friendly system for defining, running and monitoring this background work without building fragile queue infrastructure yourself.

The platform lets you define tasks and multi-step workflows in code, then handles the hard parts of executing them dependably: queuing, scheduling, retries, concurrency control, error handling, and observability into what's running and what failed. It's built for reliability and scale, so jobs don't silently disappear and you have clear visibility into your background processing — addressing common pain points with ad-hoc solutions built on raw queues, where retries, monitoring and durability are often afterthoughts that cause production headaches.

Because Hatchet is open source, teams can self-host it for full control, privacy and cost efficiency, while a cloud offering provides convenience for those who prefer it. It supports modern needs like durable execution for long-running and AI-related workflows, fan-out and orchestration patterns, and integrations with common languages and frameworks. This makes it appealing to engineering teams that need dependable background processing and workflow orchestration but want something more capable and observable than rolling their own, and more flexible or self-hostable than fully closed alternatives. As applications increasingly rely on background tasks and complex, long-running workflows — especially with AI in the mix — a solid task queue and workflow engine is foundational infrastructure. For developers who want reliable, scalable, observable background jobs and workflows, with the freedom of open source, Hatchet offers a powerful and well-designed solution.
