What is Browser Use?

Browser Use is an open-source Python library for building browser agents. You give it a task in plain language and a model to run, and it drives a browser toward that goal: reading the page, deciding what to click or type, and continuing until the task is done or it gives up.

It sits between raw browser automation and a finished product. Playwright gives you the browser. Browser Use gives you the loop around it.

How it presents the page to the model

The core problem in any browser agent is what the model sees. Browser Use extracts the page's interactive elements, buttons, links, inputs, and presents them as an indexed list with enough context to choose between them. The model picks an index and an action rather than naming a CSS selector or a coordinate.

That indexing is what makes it work reliably. A model asked for a selector will invent one that does not exist. A model asked to pick from a numbered list of the elements actually present cannot.

It can combine this with screenshots where a page needs visual understanding, at a token cost.

What building on it involves

You bring the model, and the choice matters more than with most libraries: a weaker model produces an agent that clicks the wrong things confidently. You also bring the browser, which is where most production problems appear.

The default is a local Chromium, which is fine while developing and awkward afterwards. Running many agents means running many browsers, each consuming a browser's worth of memory. Running them from a server means datacenter IP addresses and a default automation fingerprint, which is the combination that produces challenge pages on commercial sites. An agent that works on your laptop and fails in production has usually met exactly this.

Where Zenrows fits

Browser Use handles the agent loop; the browser it drives is a separate decision. Zenrows Browser Sessions provides remote browsers over the Chrome DevTools Protocol, so an agent connects to one instead of launching its own. That moves memory off your machine, allows many sessions in parallel, and routes each through residential IPs with country targeting.

Connection is a one-line change in the Puppeteer or Playwright setup underneath, so the agent code does not change.
