## What it is
A Python library that patches Selenium's ChromeDriver binary so automated Chrome sessions avoid detection by anti-bot systems like Cloudflare, Imperva, DataDome, and Distil. It automatically downloads and patches the driver and works as a drop-in replacement for webdriver.Chrome, including support for Chromium-based browsers like Brave.

## Use cases
- scrape websites protected by cloudflare
- automate browser tasks without getting blocked by bot detection
- pass datadome or imperva bot checks in selenium
- log into sites with hcaptcha using python automation
- run headless chrome that doesn't trigger anti-bot services
- web scraping with python and selenium stealth

## When to choose
- You need Selenium-based browser automation that evades common bot mitigation systems
- You want a zero-config drop-in replacement for webdriver.Chrome
- You're scraping Chromium-based sites from a residential IP and need stealth

## When to avoid
- You need IP anonymity - this does not hide your IP and datacenter IPs will often be blocked
- You need a guaranteed bypass - results vary and no guarantees are given
- You're doing simple scraping of sites without bot protection - plain requests or Selenium is simpler
