- Does the AI model run on your servers?
- No. Claude, GPT and the other models run at the AI company, such as Anthropic, OpenAI or Google. Your VPS runs the tool that talks to the model, like Claude Code, Codex CLI or OpenClaw, plus your code, files and services. That is why these tools need no GPU and fit on a small VPS.
- Which plan do I need for Claude Code?
- Claude Code lists 4 GB of RAM as its minimum, so start with VPS-S: €5.50 a month on Standard or €8.40 on Premium. Take VPS-M with 8 GB for two or three sessions, or for Docker or n8n next to the agent. Choose Premium, with the Ryzen 9 9950X, when the agent compiles code and runs test suites. One OpenClaw gateway on API models fits VPS-XS with 2 GB.
- Which AI account do I need?
- Your own. Claude Code needs a Claude Pro, Max, Team, Enterprise or Console account; it does not work on the free Claude plan. Codex CLI works with a ChatGPT Plus, Pro, Business or Enterprise plan, or an OpenAI API key. The usage limits of your plan or key apply on the VPS too. Space-Node does not sell AI usage, and none comes with the VPS.
- How do I sign in on a server without a browser?
- Claude Code shows a sign-in link. Open it on your own phone or computer, sign in, and paste the code you get into the terminal on the VPS. For Codex CLI, turn on device code login in your ChatGPT security settings and run
codex login --device-auth. For scripts and scheduled jobs, use an API key instead of a plan login. - Does my agent keep running when I close my laptop?
- Yes, as long as its process runs on the VPS. Start it inside tmux, or as a service:
openclaw onboard --install-daemon sets up a systemd service for OpenClaw. With Claude Code Remote Control, on a Pro, Max, Team or Enterprise plan, you can follow and steer that session from claude.ai/code or the Claude app. The agent stops making progress when your plan's usage limit is reached or its sign-in expires, until the limit resets or you sign in again. - Can I use OpenClaw with Claude or ChatGPT?
- Yes, with an API key: give OpenClaw an API key from Anthropic or OpenAI. For Claude models, OpenClaw's own docs (opens in a new tab) advise an Anthropic API key for new setups, because token logins expire and can be revoked. The usage and prices of the account you connect apply; Space-Node does not sell AI usage.
- How do I keep the VPS and my accounts safe?
- Log in with SSH keys and keep the system updated. Keep the OpenClaw gateway on loopback, as its docs (opens in a new tab) advise, and reach its dashboard through an SSH tunnel or Tailscale instead of opening port 18789 to the internet. Treat
~/.codex/auth.json and your API keys like passwords. Only install skills and plugins you trust, because an agent can run commands on your server. - Which operating system should I pick, and can I use Windows?
- On a Premium plan, pick Ubuntu 24.04 LTS, the image the order form marks as recommended, or Debian 13. Standard checkouts have no OS step: for a specific OS on a Standard plan, open a ticket after your order. Claude Code supports Ubuntu 20.04 and Debian 10 or newer. On Ubuntu 24.04 and later, Claude Code's sandbox needs an AppArmor profile for bubblewrap; its sandboxing docs (opens in a new tab) show the steps. Need Windows Server?
