Browser Use takes a different approach to browser automation than the Playwright and Puppeteer servers. Instead of relying purely on selectors, it gives the model both the DOM and a rendered view of the page, so it can work out what to click the way a person would. That makes it effective on the sites where conventional automation quietly falls apart.
What it actually does
The server launches a browser the agent can drive, and exposes both the structural view of the page and a visual one. The model can navigate, read, click and type, choosing targets from what it can see rather than from a selector you had to write in advance. Because it is not depending on a fixed class name, a redesign or a randomised attribute does not necessarily break the run.
Practical patterns:
- ‘Work through this multi-step checkout and tell me where it gets confusing.’
- ‘Extract the pricing table from this page, which is rendered entirely in JavaScript.’
- ‘Navigate this admin panel and find where the export button lives.‘
Why use it
Selector-based automation is excellent right up until the markup fights back: dynamically generated class names, heavy client-side rendering, layouts that shift between visits. Those are exactly the pages people most want automated. Giving the model a picture as well as the markup lets it recover in situations where a script would just throw.
Gotchas
It is meaningfully more expensive per step than selector automation, because every visual pass is tokens through your model. On a page where Playwright works, use Playwright. It is also non-deterministic in a way scripted automation is not; two runs can take different routes to the same goal, which is fine for exploration and awkward for anything you need to be repeatable. Point it at test accounts rather than production ones.
