## Definition

Browser Use is an open-source Python library ([browser-use/browser-use](https://github.com/browser-use/browser-use)) that lets an LLM drive a real Chrome instance to complete web tasks — click, scroll, fill forms, extract content — by reading the page state back to the model each step. It is the de facto harness layer between agent frameworks and the browser.

The project shipped in October 2024 from Zurich founders Gregor Zunic and Magnus Müller, joined Y Combinator W25, and [launched on HN in Feb 2025](https://news.ycombinator.com/item?id=43173378) at 3-4x the speed of ChatGPT Operator. By April 2026 it had passed 88k GitHub stars and released CLI 2.0 (Mar 22) plus the proprietary BU 2.0 model that beats Claude Opus 4.5 on web-task accuracy.

## Example

Drop the library into a Claude Code or Cursor session via its skill, give the agent a natural-language task like 'find the cheapest flight from Zurich to SFO next Tuesday and put it in my cart', and it navigates, reads DOM state, and acts — syncing your real browser profile so logged-in sessions, cookies, and MFA just work.

## Analogy

If the LLM is the driver, Browser Use is the steering wheel, pedals, and dashboard bolted onto Chrome.

## Why it's emerging now

Three April 2026 releases cemented Browser Use as the browser-automation primitive for AI agents: the BU 2.0 model (Jan 27) beats Claude Opus 4.5 on web tasks, CLI 2.0 (Mar 22) plugs straight into Claude Code and Cursor at 2x speed, and the new video-use sister skill extends the brand into editing workflows.
