What is Hatchet?

Hatchet is a managed low-latency queue for your web apps to solve scaling issues like concurrency, fairness, and rate limiting.

What is Hatchet Used for?

Hatchet is used wherever handling requests due to scaling is an issue. For example, you might use hatchet for reliably handle generative AI requests, large-scale batch jobs, and much more.

Instead of processing background tasks and functions in your application handlers, which can lead to complex code, hard-to-debug errors, and resource contention, you can distribute these workflows between a set of workers. Workers are long-running processes which listen for events, and execute the functions defined in your workflows

Is Hatchet a workflow engine?

Hatchet is designed to be a simple, reliable, and scalable way to handle background tasks and functions in your web application. While Hatchet supports full-featured and declarative DAG workflows, it's low latency design makes it a great fit for a wide range of use cases including servicing real-time requests that might be only a single function.

What is a Workflow Run in Hatchet?

A workflow run is a top level unit of work. Workflows can orchestrate multiple steps either as a DAG or by calling child workflows procedurally. If a workflow has 5 DAG steps, it will count as 1 run but child runs count as individual runs.

Does Hatchet Cloud run my compute?

Not yet, but soon. Currently Hatchet Cloud is focused on providing the best managed control plane for your workers. You can run your workers on any cloud provider or on-premises and connect them to Hatchet Cloud. We are working on a managed compute offering that will be available soon. Reach out if you're interested in pilot access.

What is a concurrent worker in Hatchet?

Each worker is a compute process that can pick up and run step runs. For example, you may have two workers: a local dev laptop and a deployed cloud worker. Often you will have many workers running in parallel to handle the load of your application.

Can I get help scoping a project with Hatchet?

Yes, we offer a demo and office hour call to help scope your project with Hatchet. You can schedule a call with our team to discuss your project and how Hatchet can help.

Is Hatchet Cloud available?

Yes, Hatchet Cloud is now available. You can sign up to get started with a free tier in Hatchet Cloud.

Is there a self-hosted version of Hatchet?

Yes, Hatchet is an MIT-licened Open Source project and instructions for self-hosting our open source docker containers can be found in our documentation. Please reach out if you're interested in paid support.

Which SDKs do you support?

We support Python, Go, and Typescript - please reach out if you're interested in other SDKs.
