Description

CloakBrowser is a custom Chromium distribution for developers building browser automation with Playwright, Puppeteer, Selenium, or CDP. Instead of relying only on runtime JavaScript patches, it changes browser behavior at the Chromium source level while preserving familiar automation APIs. Teams can adapt existing Python, JavaScript, and .NET workflows with minimal code changes and run sessions on Windows, macOS, Linux, Docker, or their own VPS infrastructure. Features include persistent profiles, reproducible browser identities, proxy-aware locale and timezone configuration, human-like input timing, and CDP server mode. CloakBrowser is intended for legitimate public-web data collection, QA, monitoring, scraping, and AI-agent workflows. The developer wrapper is MIT-licensed, while current custom Chromium binaries are distributed separately under a proprietary license. Users provide their own proxies and CAPTCHA services.

Description

Thorium implements various adjustments to the compiler configuration file, significantly enhancing browser performance, albeit at the expense of increased size. It utilizes the official builds of Chrome and incorporates Profile Guided Optimization (PGO), a strategy that leverages a profile data file produced by a profiler to refine the entire binary. This profiler conducts a preliminary run of the binary, capturing data on which code sections are most frequently accessed, their memory access behaviors, and the data they commonly retrieve. While numerous Chromium-based browsers incorporate some of these optimizations, Thorium stands out by combining all of them to deliver an exceptionally efficient browsing experience across platforms including Linux, Windows, MacOS, and Raspberry Pi. This comprehensive approach not only enhances speed but also aims to provide users with a seamless and responsive interface, making it a preferred choice for those seeking ultimate performance.
