Terms

Last updated October 1, 2026. Short, because the product is simple: you design workflows here; the agents do their work on computers you control. Relay is run by NullStack.one; “we” below means NullStack.one, and you can reach us at support@nullstack.one.

The service

Relay is in beta, and free while it is. It may change, have outages, or lose features while it grows. Keep a copy of anything important — Settings → Your data downloads everything — and export workflows you depend on to your repository, where they run without us.

Your account

• You must be at least 13, and give an email address you can receive mail at.
• Keep your password to yourself. You are responsible for what happens under your account.
• One person per account. An account holds up to 300 workflows, and a fair amount of history; the studio says when a limit is reached.

Your content

Workflows you make are yours. You give us permission to store and show them to you, and — only when you create a share link — to show that copy publicly and let others remix it. Remixes belong to whoever made them. To report a shared workflow, write to support@nullstack.one.

Acceptable use

• No using Relay to attack, spam, or break into systems you do not own, or to break the terms of the coding agents and services you connect.
• No trying to get at other people’s accounts or data, or to overload the service.
• Shared workflows must not contain anything you do not have the right to share.

We may suspend accounts that break these rules, and take down shared workflows that do.

Agents and your code

Coding agents can be wrong. Relay makes them review each other and stops unattended runs at a draft pull request, but you decide what gets merged. The agents run with the permissions of the account they are signed in to, so run them on repositories and machines you are willing to let them change. Test runs in the studio are simulations, and usage forecasts are estimates, not quotes; what the agents cost is between you and their vendors.

Relay Cloud

Relay Cloud is an invite-only beta, offered to the people we have added to it. If you use it, we run one Linux machine for you, which holds a checkout of the repositories you name and the sign-ins you make on it. It is for running Relay workflows on your own repositories and nothing else: no mining, no hosting, no workloads unrelated to a run. Places are limited, so your machine may wait for room, and it runs one run at a time. We may put it to sleep, replace it, or end the beta; where we can we will say so first, and your code is always in your repository, not only on the machine. You can remove the machine and everything on it from Settings at any time.

No warranty

The service is provided as is, without warranties of any kind. To the extent the law allows, we are not liable for indirect or consequential losses, or for anything an agent does in your repository.

Open source

The Relay CLI and this studio are developed in the open on GitHub, under the MIT license in that repository. These terms cover the hosted service; the license covers the code.

Changes

If these terms change in a way that matters, we will say so in the studio first. Using Relay after that means you accept the new terms; deleting your account means you do not have to.
