## What it is
CloakBrowser is a stealth Chromium distribution with 73 source-level C++ fingerprint patches that passes major bot-detection systems like Cloudflare Turnstile and FingerprintJS. It ships as a drop-in Playwright/Puppeteer replacement for Python, JavaScript, and .NET, with a humanize mode for human-like input behavior.

## Use cases
- scrape websites protected by Cloudflare Turnstile
- automate a browser without getting flagged as a bot
- replace Playwright with a stealth browser in existing scripts
- pass FingerprintJS and BrowserScan detection tests
- run headless browser automation at scale for data collection
- get a high reCAPTCHA v3 score for automated browsing
- build AI agents that browse the web undetected

## When to choose
- you need a drop-in Playwright/Puppeteer swap that evades antibot systems
- config-level stealth patches keep breaking on Chrome updates and you want source-level patches
- you want behavioral humanization (mouse curves, keyboard timing) with one flag
- you need cross-platform binaries for Linux, Windows, and macOS with Docker support

## When to avoid
- you only need standard browser automation on sites without bot detection - plain Playwright is lighter
- your use case requires bypassing CAPTCHAs in ways that may violate site terms of service or local law
- you need a pure-Python or pure-JS solution without downloading a compiled Chromium binary
- you need fine-grained control over the Chromium build itself
