CloakBrowser

CloakBrowser is an open-source stealth browser automation platform built around a custom Chromium distribution with deep fingerprint-resistance modifications. Unlike traditional browser automation tools that rely primarily on injected JavaScript patches, CloakBrowser applies source-level Chromium modifications affecting WebGL, canvas rendering, audio fingerprints, fonts, GPU reporting, WebRTC behavior, and automation detection signals. The project integrates with Playwright and Puppeteer while preserving familiar automation workflows for developers. It also supports isolated browser profiles with configurable fingerprints, making it useful for testing, automation research, scraping, QA, and multi-profile browser environments. The ecosystem includes a self-hosted browser profile manager that functions as an open-source alternative to commercial anti-detect browsers.
