The Distributed Task Queue for More Resilient Web Applications

Hatchet is a distributed, fault-tolerant task queue which replaces traditional message brokers and pub/sub systems - built to solve problems like concurrency, fairness, and durability.

Backed by YCombinator

Hatchet handles common scaling challenges.

Fairness for Generative AI
Don't let busy users overwhelm your system. Hatchet lets you distribute requests to your workers fairly with configurable policies.

Building Blocks for Scale.

Hatchet is engineered for the scaling challenges you have today and the ones you'll have tomorrow.

Low Latency, High Throughput Scheduling.

Hatchet is built on a low-latency queue (25ms average start), perfectly balancing real-time interaction capabilities with the reliability required for mission-critical tasks.

Concurrency, Fairness, and Rate limiting.

Enable FIFO, LIFO, Round Robin, and Priority Queues with built-in strategies to avoid common pitfalls.
