Run Claude Code and Codex in the cloud on your own subscription.

Getting started

Three steps, then walk away.

1. Create the agent — Pick Claude Code, Codex or Gemini CLI. Manyfold provisions the machine and installs the CLI on it.
2. Sign in to use your subscription — Open the sign-in terminal. It starts already running the CLI’s own sign-in command, so all you do is follow the printed link, paste the code back, and refresh. claude auth login --claudeai Codex signs in with a device code, which may need enabling in your ChatGPT security settings first.
3. Give it work and close the tab — The turn runs on the runtime, not in your browser. Losing wifi or shutting the lid changes nothing.

What it is for

What people use it for.

• “I thought of the fix on the train.” Send it from your phone.
• “Six issues, one laptop.” Six machines, six branches.
• “I am not letting it run loose on my Mac.” It is not on your Mac, so your keys and other projects never leave it. Skip every prompt.
• “I do not want a second AI bill.” Use the subscription you have.

What it costs

Your subscription already pays for the model.

• Your own subscription — Nothing extra. Sign in inside the machine. You already pay for it.
• Your own API key — Billed by them. or any endpoint you run
• Manyfold managed models — Billed by us. No key to go and get. Paid from credit.

And Manyfold itself is free to start. Start on the free plan: Up to 3 agents, No card needed.

Questions

Before you sign up.

Can you see my code, or my account?

Each agent gets its own machine, with its own kernel, its own disk and its own login. The sign-in token is written by the CLI onto that machine’s disk, not by us, and your working files live there too — while your SSH keys, your credentials and your other projects never leave your laptop.

Will this use up my plan limits faster?

It is your plan, so the same limits apply, set by Anthropic or OpenAI. Manyfold adds nothing on top: no markup, no second meter. What changes is that the plan can now be busy while you are asleep, and on several branches at once.

If I close the tab, does it stop?

No. The turn runs server-side. Close the tab, lose wifi, shut the lid; come back later and the transcript is there, finished.

Can I use an API key instead of my subscription?

Yes. Paste a key for Anthropic, OpenAI, Google Gemini, OpenRouter or NetMind, point at your own endpoint, or use Manyfold’s managed models and pay from a credit balance. It is one choice per agent, on purpose: the subscription sign-in and a stored key are mutually exclusive, so a key you pasted can never be silently ignored.
