Comet Lab Atlas

An open-source library that lets an AI agent control a browser from natural-language goals.

Browser Use sits between a model and a browser. You give it a goal in plain language; it inspects the page, decides the next action, and drives the browser to carry it out — looping until the task is done.

It is one of the most-used open-source projects for agentic browsing, and it pairs the intelligence layer with the mechanical one so you do not script every click.

Where it's ideally used

A fit when an agent must complete goal-directed tasks on sites with no API, and the steps vary too much to script by hand.

Where it doesn't fit

Less reliable than a fixed script for a stable, repetitive flow — when the steps never change, scripting them is steadier and cheaper.
