Browser Use

An open-source Python library that gives AI agents the ability to control a real web browser — navigating pages, filling forms, clicking buttons, and extracting data.

Works with Claude, Gemini, OpenAI, and local models. Self-host for free or use Browser Use Cloud for managed stealth browsers and parallel execution.

What This Skill Does

Core Capabilities

  • Web Automation: AI agents that browse the web like a human — click, type, scroll, navigate
  • Multi-LLM Support: Works with Claude, GPT-4, Gemini, and local models via a unified interface
  • Form Handling: Fill and submit forms, handle auth flows, multi-step checkout
  • Research Tasks: Gather information across multiple sites in a single agent run
  • Cloud Option: Browser Use Cloud provides stealth browsers and parallel execution at scale
  • Custom Tools: Extend agents with your own tool definitions

Installation

BASH
# Initialize a new project
uvx browser-use init

# Or add to existing project
uv add browser-use

Quick Start

PYTHON
from browser_use import Agent
from langchain_anthropic import ChatAnthropic

agent = Agent(
    task="Find the best laptop deals under $1000 and summarize them",
    llm=ChatAnthropic(model="claude-sonnet-4-5"),
)

await agent.run()

Use Cases

  1. E-commerce research: Compare prices across multiple retailers
  2. Lead generation: Gather contact information from directories
  3. Form automation: Fill and submit repetitive web forms
  4. Content monitoring: Track changes on websites over time
  5. QA testing: Automate end-to-end user flow testing
  6. Data extraction: Scrape structured data from any website

Fine-Tuned Model

Browser Use offers a proprietary fine-tuned model optimized for browser automation:

  • browser-use/bu-30b-a3b-preview — 3–5x faster than general-purpose models with state-of-the-art accuracy on browser tasks
  • Available via Browser Use Cloud

Browser Use Cloud

For production workloads, Browser Use Cloud provides:

  • Stealth browsers that bypass bot detection
  • Parallel execution across multiple browser instances
  • Managed infrastructure — no setup required
  • Pricing: $0.20/M input tokens, $2.00/M output tokens

Persistent Sessions

Use the CLI for browser sessions that persist across agent runs:

BASH
browser-use --task "Log into my dashboard and check today's metrics"
