Basic Fingerprinting

Simple PHP page that shows what a server and a browser can see about a visitor. It combines HTTP request details from PHP with client-side signals from JavaScript.

Features

• Server-side snapshot of key HTTP fingerprinting signals with JSON access.
• Client-side summary for languages, GPU, CPU cores, and screen metrics.
• Device class inference based on screen size/DPR presets.
• GeoIP (ipapi.co) on-demand with OpenStreetMap preview.
• Tor exit DNS check + proxy/VPN heuristic from forwarding headers.
• FR/EN UI with automatic detection and user toggle.
• Access logging to daily .log files in src/logs/.
• Security headers + no-cache via .htaccess.

Usage

1. Deploy the src/ directory to any PHP-capable web server.
2. Ensure Apache mod_headers (and optionally mod_rewrite) is enabled if you want the .htaccess rules to apply.
3. Open the page in a browser. GeoIP runs only after clicking the button.

Development

• Entry point: src/index.php
• Apache config: src/.htaccess
• Styles: src/styles.css
• JS: src/app.js (helpers in src/app-utils.js, i18n in src/i18n.js)
