Overview
CloakBrowser offers a revolutionary approach to bypassing bot detection, delivering a truly stealthy Chromium experience. Unlike solutions that rely on JavaScript injections or configuration patches, CloakBrowser modifies the Chromium binary at the C++ source level. This means it's not a "patched config" or "JS injection" – it's a genuine Chromium browser with its inherent fingerprints meticulously altered. As a result, CloakBrowser consistently scores as a normal browser across a comprehensive suite of bot detection tests, including Cloudflare Turnstile, reCAPTCHA v3, and FingerprintJS.
Key Features
- Source-Level Fingerprint Patches: Boasts 49 C++ source-level patches that modify fingerprints at the binary level, covering canvas, WebGL, audio, fonts, GPU, screen, WebRTC, and more. This provides a deeper and more resilient level of stealth than surface-level modifications.
- Drop-in Playwright/Puppeteer Replacement: Seamlessly integrates with existing Playwright and Puppeteer workflows. Simply swap your import statement, and your automation scripts will benefit from CloakBrowser's advanced stealth capabilities without code rewrites.
- Humanization Capabilities (
humanize=True): Features like human-like mouse curves, keyboard typing, and scroll patterns can be enabled with a single flag, passing behavioral detection tests with ease. - Unparalleled Detection Evasion: Achieves a 0.9 reCAPTCHA v3 score, passes Cloudflare Turnstile and FingerprintJS, and successfully evades 30+ detection sites, including bot.incolumitas.com and deviceandbrowserinfo.com.
- Automatic Updates & Zero Configuration: The stealth Chromium binary auto-downloads on first launch and checks for updates in the background, ensuring you're always on the latest stealth build with minimal setup.
- Free and Open Source: No subscriptions or usage limits, providing a cost-effective and transparent solution for your automation needs.
- Browser Profile Manager: A self-hosted, open-source alternative to commercial profile managers, enabling the creation of unique browser profiles with custom fingerprints and proxies.
Typical Use Cases
- Web Scraping: Circumvent bot detection on websites that block standard automation tools, enabling reliable data extraction.
- Automated Testing: Ensure your web applications are tested against realistic user behavior and bypass anti-bot measures during QA processes.
- Digital Marketing Automation: Execute campaigns and monitor performance without being flagged as a bot.
- Account Management: Manage multiple accounts or perform repetitive tasks across various platforms that employ strict bot detection.
- AI Agent Development: Power AI agents that require natural browser interaction to perform tasks, such as browsing and information gathering.
