Clearcote

Product Introduction

1. Overview: Clearcote is an open-source, de-Googled Chromium browser specifically engineered for web automation and anti-detection. It modifies the browser engine at the source-code level to provide coherent, plausible digital identities.
2. Value: It enables developers and automation engineers to run browser scripts that blend in with real user traffic by providing stable, non-unique browser fingerprints, directly addressing the core challenge of bot and automation detection.

Main Features

1. Engine-Level Fingerprint Control: Unlike script-based solutions that inject JavaScript, Clearcote's identity controls are compiled directly into the Chromium binary. This provides native, undetectable behavior for critical APIs like navigator.webdriver, WebGL, Canvas, and AudioContext, making automation sessions appear as genuine user browsers.
2. Drop-in Automation SDKs: Clearcote offers native, seamless integration with leading browser automation frameworks. It provides dedicated npm and PyPI packages for Playwright and Puppeteer, allowing users to switch their existing scripts to Clearcote by simply pointing to its binary, with no API changes required.
3. De-Googled & Privacy-First Base: Built on the ungoogled-chromium project, it strips out all Google services, telemetry, and background communication. This ensures privacy by default, eliminates phone-home data leaks, and provides a clean, reproducible build foundation for security-conscious users.

Problems Solved

1. Challenge: Modern websites use advanced browser fingerprinting techniques (e.g., via libraries like CreepJS or BrowserScan) to detect and block automated scripts, bots, and headless browsers by identifying inconsistent or artificial browser signals.
2. Audience: This tool is essential for developers in web scraping, data aggregation, automated testing, ad verification, and security research who need reliable, undetected browser automation.
3. Scenario: A data scientist needs to scrape pricing information from an e-commerce site that employs aggressive anti-bot measures. Using Clearcote with Playwright, their script presents a consistent, realistic fingerprint (covering TLS JA3/JA4, hardware concurrency, timezone, and WebGL renderer), allowing uninterrupted data collection.

Unique Advantages

1. Vs Competitors: Unlike proxy-based solutions or JavaScript patching libraries (e.g., Puppeteer-extra-plugin-stealth), Clearcote operates at the engine level. This results in fundamentally more stable and less detectable fingerprints, as it avoids the tell-tale signs of runtime DOM patching that advanced detectors look for.
2. Innovation: Its use of a seed-based system to generate a "coherent per-site identity" is a significant technical edge. All fingerprintable attributes (from User-Agent to screen geometry) are derived deterministically from a single seed, ensuring all signals are consistent with each other—a concept inspired by and extending beyond Brave's farbling techniques.

Frequently Asked Questions (FAQ)

1. How does Clearcote differ from Puppeteer Stealth Plugin? Clearcote modifies the Chromium browser engine itself, providing native fingerprint control. The Stealth Plugin injects JavaScript to patch APIs at runtime, which can be detected by scripts checking for function hooking or inconsistencies in native code behavior.
2. Is Clearcote detectable by services like CreepJS or BrowserScan? Clearcote is specifically designed to pass advanced fingerprinting tests. By controlling over 30 key browser signals at the engine level—including navigator.webdriver, WebGL parameters, and TLS fingerprints—it aims to achieve a 0% detection rate on these platforms, presenting as a "real machine."
3. Can I use my existing Playwright/Puppeteer scripts with Clearcote? Yes. Clearcote is designed as a drop-in replacement. You install its SDK (pip install clearcote or npm install clearcote), and your existing code only needs to change the launch command to point to the Clearcote binary, maintaining full API compatibility.
