A Rust crate to generate stealth JavaScript that spoofs browser fingerprinting features. Useful for emulateting real browser profiles across different platforms. It is recommended to use this project with headless-browser for real profiles and the latest chrome versions.

• Mimic real user fingerprints using static profiles
• Help avoid common browser automation detection methods
• Generate scripts for injection into browser environments

• Tiered spoofing levels (basic to full)
• WebGL and GPU spoofing (WIP)
• navigator.userAgentData high entropy value support
• Plugin and mimeType spoofing
• Optional mouse and viewport spoofing
• Platform-specific variants (macOS, Windows, Linux)

use spider_fingerprint::{build_stealth_script, builder::{Tier, AgentOs}};
let script = build_stealth_script(Tier::Full, AgentOs::Mac);
// Inject `script` into a browser context

This crate provides multiple spoofing levels depending on the desired realism and complexity.

| Tier            | Description                                               |
|-----------------|-----------------------------------------------------------|
| `Basic`         | Chrome props, WebGL spoofing, plugins/mimeTypes           |
| `BasicNoWebgl`  | Same as Basic but skips WebGL spoofing                    |
| `Mid`           | Adds WebDriver hiding                                     |
| `Full`          | All spoofing including WebGPU adapter spoof               |

You can override the default Chrome versions with the env configs:

CHROME_VERSION=135 
CHROME_NOT_A_BRAND_VERSION="99.0.0.0"
