Run Claude Code in the browser, on a machine that stays up
Claude Code is Anthropic's agentic coding CLI. It is at its best on long tasks — a refactor across many files, a test suite brought back to green, a migration written and checked — and those are exactly the tasks that outlast the session you started them in.
Running it on a laptop ties the work to the laptop. Here it runs on a machine of your own that is already on, already has your repositories, and is reachable from whatever browser you happen to be in front of.
How it arrives
- On the machine
- Installed as part of the build
- How you run it
- A command line tool — you run it in a terminal tab
We did not write Claude Code. It is anthropics/claude-code. We install it on every machine and put it behind the login.
Start it, close the tab, come back
The machine is a real VM that keeps running when you close the tab. A process you start does not stop because your laptop slept, your train went into a tunnel, or you switched to your phone.
The terminal is a persistent session, not a shell that dies on disconnect. Opening the dashboard again puts you back in the same session with the scrollback intact — the agent kept working while nothing was watching it.
It is a real machine, not a sandbox
Claude Code can install packages, run your test suite, start your dev server, and talk to the internet, because it has a whole Ubuntu machine and root on it. Nothing is stubbed and no capability is withheld to make the environment safe to share — the machine is not shared.
Your API key is yours. Bring it, keep it on the machine, and the agent uses it directly.
It is not the only one installed
Codex, OpenCode, Gemini CLI and Kimi CLI are on the same machine, against the same files. Comparing two agents on one task is opening a second tab, not provisioning a second environment.
Questions
- Does Claude Code keep running when I close the browser?
- Yes. It runs inside a persistent terminal session on the machine, not in the browser. Closing the tab disconnects the view and leaves the process running.
- Do I need my own Anthropic API key?
- Yes. The CLI is installed and ready; the account it bills to is yours, and the credentials stay on your machine.
- Can I use Claude Code and another agent at the same time?
- Yes. Every machine has Claude Code, OpenAI Codex, OpenCode, Gemini CLI and Kimi CLI installed, and they share the same filesystem and toolchain.
Once you have one
It comes with the machine
Every tool on this site is installed on every machine. You are choosing a size, not a bundle.
