# Run your browser tasks on autopilot with AI agents

Unlimited profiles. Unlimited possibilities. Everything you can do\
in a browser, your agent can do too. Way faster and at scale.

[Download the app](https://scalebrowser.net/download)

[Start 7-day free trial](https://scalebrowser.net/register)

* MCP

  Point Claude, Cursor or your own agent at it, over HTTP or stdio.

  Python and Node, both on direct CDP, plus a plain REST API. Keep your agent logic, swap the browser underneath it.

* Direct CDP

  Already running browser-use? One line of connection code and the run starts signed in.

> I use it to run about thirty agents that each need their own logged in account. Since every agent needs a separate identity I wanted something where the profile stays the same between runs.
>
> It keeps the session, the cookies and the passkeys per profile. I haven't had to restart the nightly run since June.
