Open Source · Modular · Programmable Anti-Detection Browser
Undetectable Fingerprint Browser is a highly customizable, realistically emulated, automation-friendly anti-detection browser, specifically designed to counter modern websites' advanced fingerprinting and detection systems.
Whether you're engaged in anti-anti-scraping research, marketing analytics, multi-account management, or need to build a fully controllable browser automation environment, this project is your ultimate choice.

Not just spoofing more — but spoofing better and more realistically, with global consistency.
| Fingerprint Type | Feature Description |
|---|---|
| Canvas Fingerprint | Precision spoofing, random noise, custom rendering results |
| WebGL & WebGL2 | Fake GPU models, render returns, renderer strings, antialias settings |
| AudioContext Fingerprint | Alters audio behavior to return stable spoofed results |
| ClientRects / DOMRect | Emulates browser-specific rendering differences |
| Font Fingerprint | Controls font detection responses to block OS font probing |
| Timezone / Language | Global override of navigator, Intl API, Date outputs |
| Hardware Concurrency | Custom CPU core count |
| Device Memory | Spoof navigator.deviceMemory values |
| Screen Resolution & Color Depth | Simulates different screen sizes and color depths |
| Touch / Mobile Indicators | Emulates mobile device indicators: touch events, UA, media queries |
👉 Exclusive Feature: Consistency Analysis Engine ensures all spoofing fields align logically and do not conflict, eliminating detection signals at the root.
We’ve integrated a complete anti-leak system — no extra installation required for:
- ✅ WebRTC leak prevention
- ✅ Auto-adaptive Canvas/WebGL spoofing
- ✅ Automation module (Puppeteer / Playwright compatible)
- ✅ Built-in proxy injection (SOCKS5, HTTP, TLS proxy)
- ✅ GPS & sensor data emulation
- ✅ Local JS injection with CSP bypass support
Seamlessly integrate this browser into any automation pipeline, or fully control it programmatically.
- Just add a startup parameter — no need to modify code.
- Puppeteer: Works by pointing to custom Chromium binary
- Playwright: Fully compatible with Chromium engine
- DevTools Protocol and WebSocket control support
- JavaScript API and CLI tools for advanced tuning and scripting
