Undetectable Fingerprint Browser is an open-source, automation-friendly anti-detection browser that spoofs digital fingerprints across canvas, WebGL, audio, fonts, timezone, and hardware parameters to bypass website detection systems.

It supports integration with automation frameworks like Puppeteer and Playwright, includes built-in WebRTC leak prevention and proxy injection, and provides customizable fingerprint profiles for multi-account management and web scraping. The tool is designed as a free alternative to commercial solutions like Multilogin and includes a consistency analysis engine to ensure spoofed fingerprints do not conflict and trigger detection.
