Undetectable is an anti-detect browser designed for managing multiple accounts on social networks and other platforms. It allows users to create an unlimited number of browser profiles, each with unique digital fingerprints, by substituting device and browser data such as UserAgent, OS, screen resolution, cores, memory, browser settings, languages, WebGPU, WebGL, WebRTC, and geolocation. The browser supports proxy management (Socks5, HTTP/HTTPS), cookie automation, and integration with tools like Puppeteer, Playwright, and Selenium for browser automation via API. It offers features like mass profile creation, a synchronizer for mirroring actions across profiles, and a cookie bot with a Popular Website Generator to simulate natural browsing behavior. Undetectable is built on a custom Chromium fork (Stealthium) and supports Windows 10/11 and macOS (Big Sur and later). It ensures high security and privacy, distinguishing itself from standard proxies or VPNs, and is used for tasks like traffic arbitrage, affiliate marketing, e-commerce, and managing multiple social media accounts.
