Browser Use Undetected

An undetected browser automation wrapper/addon for browser-use that provides stealth capabilities using Camoufox (Firefox-based) & proxies to avoid detection by anti-bot systems, with local ReCAPTCHA v2/v3 solving & cloud solving almost all other bot detection systems using CapSolver API

Features

• Stealth Browser Session: Uses Camoufox for undetected browsing
• Proxy Support: Built-in proxy configuration
• Captcha Solving: Automatic captcha detection and solving using local methods & cloud (paid) services
• Drop-in Replacement: Easy integration with existing browser-use code

You can find demos near the bottom of the page.

Issues

• Humanizer setting does not work with comboboxes/dropdowns
• Captcha solving not fully functional/tested
• Unable to enter extra arguments in agent specifically for camoufox
• Oxylabs is not a great provider, includes restricted targets for resedential proxies

Installation

Requires:

python 3.11 - 3.13

In terminal:

pip install browser-use-undetected
camoufox fetch

Add .env variables:

# proxy settings (optional) - can set using Agent arguments or globally
PROXY_USERNAME=
PROXY_PASSWORD=
PROXY_HOST=
PROXY_PORT=

# Capsolver API Key (optional) - for fallback captcha solving
# Get your API key from https://capsolver.com/
CAPSOLVER_API_KEY=

Quick Start

import asyncio
from dotenv import load_dotenv
load_dotenv()
from langchain_openai import ChatOpenAI
from browser_use_undetected import StealthAgent, PROXY


async def main():
    agent = StealthAgent(
        task="Find a cheap Iphone <$500 using google",
		llm=ChatOpenAI(model="gpt-4.1-nano-2025-04-14"),
		#humanize=True, #Human movement, currently comboboxes/dropdowns do not work with this
        proxy=PROXY(), # Optional
		#proxy={
		#	"server": "http://proxy:port", 
		#	"username": "user", 
		#	"password": "pass"
		#},
        auto_solve_captchas=True,  # Optional
        capsolver_api_key="your_capsolver_key"  # Optional
    )

    result = await agent.run()
    print(result)


if __name__ == "__main__":
    asyncio.run(main())

Advanced Usage

Using StealthBrowserSession directly

from browser_use_undetected import StealthBrowserSession
from browser_use.agent.service import Agent

# Create a stealth browser session
browser_session = StealthBrowserSession(
    proxy={"server": "http://proxy:port", "username": "user", "password": "pass"},
    auto_solve_captchas=True,
    capsolver_api_key="your_capsolver_key"
)

# Use with regular Agent
agent = Agent(
    task="Your task here",
    llm=your_llm_instance,
    browser_session=browser_session
)

Proxy Configuration

from browser_use_undetected import PROXY

# Use predefined proxy format
proxy_config = PROXY(
    host="proxy.example.com",
    port="8080",
    username="user",
    password="pass"
)

agent = StealthAgent(
    task="Your task",
    llm=your_llm_instance,
    proxy=proxy_config
)

Configuration Options

• proxy: Proxy configuration dict or PROXY object
• auto_solve_captchas: Enable automatic captcha solving (default: True)
• capsolver_api_key: API key for CapSolver service
• All other browser-use Agent parameters are supported
