--on-idle suspend) and the VM is suspended on its own after a window of sustained inactivity.
What if I run out of credits? When your balance drops to your account’s suspension threshold — the amount needed to store your snapshots, images, and disks for 7 days, shown by machine0 account — running machines are snapshotted and destroyed. Snapshots are retained — top up and recreate. Disks are kept (they hold your data) and keep billing until you remove them; recreated VMs don’t reattach them automatically — pass --attach disk:<name> again. Auto-topup prevents this and is on by default once you have a saved card; you can turn it off from the Account page in the web dashboard.
What tools are pre-installed? The ubuntu-24-04-loaded image includes Docker, Node.js, Python, Go, Rust, Bun, Claude Code, Codex, OpenCode, tmux, zoxide, fzf, ripgrep, and bat. See Images.
Can I export my data? Yes. SSH in and copy anything, or use machine0 sync pull. With NixOS, your OS config is portable to any NixOS host.
Can I use my own SSH key? Yes, that’s the default. The CLI registers your ~/.ssh/id_rsa.pub on first use. See SSH.
