A Linux desktop for your agent

1 October 2026

An agent that uses a computer needs a computer to use. Lending it your own laptop means lending it your files and your accounts, and keeping the lid open. A fresh headless browser per task forgets every login, and you cannot see what happens in it.

computeruse sessions sit between the two. A session is a small Linux desktop in the cloud, with Chromium open on it:

• The agent operates it over MCP. Every session has its own endpoint. Add it to Claude or another MCP client. The agent writes JavaScript with run_js, and that code drives the browser.
• You watch, and take over. The desktop is on your screen, in the page. Sign in to a site yourself, solve the captcha, then hand back.
• It remembers. The disk persists, so logins and tabs are there next time. An idle session sleeps; the next call wakes it with the screen as it was.
• It is isolated. One sandbox, one disk and one endpoint per session. Use one per task or per client, and delete it afterwards.

What it is not, yet

The desktop is minimal: a display, a window manager and Chromium. There is no terminal and no other application.

The agent acts on web pages today. Using the mouse and keyboard on the whole desktop is planned. Policies per session, API tokens and a Terraform provider are built and not enabled yet. The status page says what is live.
