Questions

Am I billed when a sandbox is stopped?+

No. Stopping snapshots the sandbox and pauses billing. Resume any time in a few seconds.

Is the $20/mo a per-sandbox minimum?+

No. It is the account total, and it converts into 555 hours of machine time to spend across any number of sandboxes.

Where do sandboxes run?+

In secure, single-tenant VMs across US and EU regions. Your data and snapshots stay in-region.

What survives stop and resume?+

Your files, installed packages, and enabled systemd services. Hand-run processes need a restart.

Can I give sandboxes to my own users?+

Yes. Create them no-env so they receive none of your account's secrets and stay confined to themselves.
