# πŸ•΅οΈβ€β™‚οΈ Undetectable Fingerprint Browser  



[中文介绍](https://github.com/itbrowser-net/undetectable-fingerprint-browser/blob/main/README_zh.md)



**Open Source Β· Modular Β· 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.

## πŸš€ Key Highlights



### 🧠 1. Comprehensive Fingerprint Spoofing



> Not just spoofing more β€” 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 |



πŸ‘‰ **Exclusive Feature: Consistency Analysis Engine** ensures all spoofing fields align logically and do not conflict, eliminating detection signals at the root.

### 🧩 2. Fully Supported & Built-in Modules



We’ve integrated a complete anti-leak system β€” no extra installation required for:



- βœ… WebRTC leak prevention  

- βœ… Auto-adaptive Canvas/WebGL spoofing  

- βœ… Automation module (Puppeteer / Playwright compatible)  

- βœ… Built-in proxy injection (SOCKS5, HTTP, TLS proxy)  

- βœ… GPS & sensor data emulation  

- βœ… Local JS injection with CSP bypass support

### πŸ€– 3. Automation-Ready



Seamlessly integrate this browser into any automation pipeline, or fully control it programmatically.



#### 🀝 Full Framework Compatibility:



- Just add a startup parameter β€” 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

## πŸ”§ Quick Start  

# Install Pre-Compiled Version  

Download and extract the pre-built package: [Compiled Binary Release](https://github.com/itbrowser-net/undetectable-fingerprint-browser/releases/download/v1.0.0/fingerprint_browser_v1.0.7z).  



**Generate a Fingerprint via Command Line**  

```bash  

./itbrowser_fingerprint.exe  

```



**Launch the Browser with a Specified Fingerprint**  

```bash  

chrome --itbrowser=myfingerprint.json  

```



**For Automation Use:**  

```bash  

chrome.exe --user-data-dir=data1 --itbrowser="D:\Program Files\chrome\1.json" --proxy-server="socks5://someuser:password@host:port" --remote-debugging-port=9222  

```



# build the project from source

git clone https://github.com/itbrowser-net/undetectable-fingerprint-browser.git

merge the code with chromium source code.
