Getting started

This guide walks through the first sandbox flow: sign in, choose a repository, start a sandbox, and ask the agent to make a small change.

1. Sign in

Open Nimbus and sign in with the email you use for your workspace. If your account needs GitHub access, connect GitHub before creating a sandbox.

2. Create a sandbox

Choose a repository and branch. Nimbus will create a cloud sandbox, clone the repository, install the runtime tools, and report setup progress in the app.

3. Wait for setup

A sandbox is ready when it shows running and setup is complete. If setup fails, open the sandbox details and inspect the setup logs before retrying.

4. Send a prompt

Ask for a focused change. Good prompts include the target behavior, files or screens involved, and how you expect the result to be verified.

Update the pricing page so the Standard plan shows 8M sandbox seconds and a $0.10/hour overage rate. Run the relevant checks and tell me what changed.

5. Review and iterate

Use the changes panel to review diffs. If the change touches a UI, open the forwarded preview port and inspect it in the browser.

Verification checklist

• The agent turn reaches a completed assistant response.
• The diff only contains expected files.
• Any local checks or app previews match the requested behavior.
• Disposable test sandboxes are cleaned up when no longer needed.
