Projects
Open source tools, research projects, and utilities I've built for fingerprinting and bot detection.
Open source library to detect bots and crawlers using browser fingerprinting. Analyzes fingerprint inconsistencies to identify popular bot frameworks: Selenium, Puppeteer, Playwright, and headless Chrome.
Fingerprinting
Bot Detection
Open Source
Detection database containing over 35M+ verified proxy IPs, updated every 2 hours. Covers residential, data center, and ISP proxies. 100% proprietary and curated data using active proxy enumeration.
Proxy Detection
IP Intelligence
Anti-Fraud
Free, daily-updated lists of proxy IPs used by bots. Includes 500k verified proxy IPs sample, plus 5-day and 8-day aggregated block lists with confidence scores for direct blocking or risk scoring.
Open Source
Proxy Detection
Block List
Comprehensive list of disposable and temporary email providers with their associated domains. Covers services like YOPmail, Mailinator, temp-mail, and privacy-focused forwarding services.
Fraud Detection
Email Validation
Data
Implementation of canvas fingerprinting inspired by Elie Bursztein's Picasso paper. Can be used for bot detection and as a proof-of-work mechanism with adjustable difficulty.
Fingerprinting
Canvas
Open Source
Test if your browser or bot is detected using fingerprinting signals. Checks for WebDriver, CDP automation, headless Chrome, inconsistent GPU/WebGL, and more. Pure fingerprinting detection, no IP reputation or behavior analysis.
Bot Detection
Testing
Playground
Online tool to view your browser fingerprint and calculate a bot risk score. Displays canvas fingerprint, IP address, HTTP headers, and browser extensions.
