CreepJS is a web application that performs advanced device and browser fingerprinting to expose weaknesses in anti-fingerprinting browsers and privacy extensions. It detects JavaScript tampering, lie patterns, and high-entropy APIs to test how resistant a browser setup is to tracking.
Use cases
- test how well my browser resists fingerprinting
- check if my anti-fingerprinting extension leaks data
- compare privacy protection of Brave vs Tor Browser
- detect spoofed user agent and canvas lies
- audit browser privacy settings for entropy leaks
- research browser fingerprinting techniques
When to choose
- you want to evaluate the fingerprinting resistance of a browser or privacy extension
- you are researching anti-fingerprinting weaknesses and lie detection
- you need a self-hosted fingerprint test page
When to avoid
- you need a production fingerprinting library for user tracking - the project explicitly is not one
- you need a programmatic API or SDK rather than a web test page
- you require a commercially licensed tool - the CreepJS name is trademarked and public mirrors are prohibited
