Clearcote is an anti-detect browser for developers: a real Chromium build with fingerprint control done at the C++ engine level, not a JavaScript shim or a Playwright patch. It controls canvas, WebGL, AudioContext, fonts, the User-Agent and UA-CH client hints, timezone, hardware concurrency, TLS/JA3, WebRTC and navigator.webdriver, and keeps them coherent, so the values a page reads agree with each other. It is de-Googled and drives like stock Chromium through SDKs for Playwright and Puppeteer in Node.js, Python and .NET. The open build ships every change as a readable patch, rebuilds from source, and every release is checksummed and GPG-signed. The open build and SDKs are free and open source (BSD-3); the latest licensed build has a free tier for one browser at a time, and paid plans add concurrent browsers, server-side personas and hosted browsers. Built for lawful automation, web scraping, QA testing and privacy.
