Hatchet
Also known as: Hatchet Cloud
Durable orchestration engine for AI agents, background tasks, and mission-critical workflows, built on PostgreSQL with automatic retries, checkpointing, and observability, available as managed cloud or MIT-licensed self-host.
Hatchet is a San Francisco company (Y Combinator Winter 2024, founded by Alexander Belanger and Gabe Ruttner, both prior YC CTOs) building a durable orchestration engine for AI agents, background tasks, and mission-critical workflows on a single platform. Tasks are defined as simple functions in Python, TypeScript, Go, or Ruby and composed into durable workflows with automatic retries, timeouts, cron and scheduled runs, complex pause/resume conditions using durable sleep and event waits, priority, rate limiting, and fair scheduling with concurrency policies. It uses PostgreSQL as a durability layer for both the task runtime and observability, persisting every task and agent invocation in a durable event log for debugging, retries, and replays, which lets agents automatically checkpoint state and recover from failure. The orchestration engine is available as Hatchet Cloud or fully self-hosted, is 100 percent MIT licensed, and has been battle-tested processing over a billion tasks per month, with the open-source offering deployed more than 10,000 times monthly. Workers run on the customer's own infrastructure while the engine can be managed or self-hosted.

Recent platform changes
Hatchet introduced idempotency keys to ensure workflows execute exactly once, and batch tasks to automatically aggregate multiple tasks into a single run. The release also includes hatchet-embedded for running a sidecar engine during local development, and a Slot Cost API to manage worker resource allocations.
Bears on: Memory / state
View sourcePricing
Free and open source to self-host under the MIT license, with PostgreSQL as the only required dependency; Hatchet Cloud is a managed service used by hundreds of companies, available to sign up and try.
Open-source self-host free; Hatchet Cloud managed service usage.
Cost watchouts
Self-host cost is your own Postgres and infrastructure and operational burden at high task volumes; Hatchet Cloud cost scales with task throughput, and the site does not publish exact cloud rate cards.
Variable cost rationale
Self-host shifts cost to your own Postgres and compute at scale; Cloud cost scales with task volume, which can be very high for heavy workloads.
Overage / add-ons
Self-host scales with your own infrastructure; Cloud usage scales with task throughput.
Sales call required
No, self serve available
Free / trial
Self-hosting is free under MIT; Hatchet Cloud can be signed up for and tried.
Lowest paid plan
Self-host at zero dollars; Hatchet Cloud rates not published in retrieved sources.
