A demonstration web application that assigns persistent unique identifiers to website visitors via favicon-based browser fingerprinting. It is intended for educational and demonstration purposes to raise awareness of this tracking technique.
Use cases
- demonstrate favicon-based browser fingerprinting
- test whether a browser or privacy tool blocks favicon tracking
- research persistent tracking methods that survive cache clearing and incognito mode
- educate users about browser fingerprinting risks
- self-host a fingerprinting demo server
- evaluate the effectiveness of VPNs and adblockers against favicon tracking
When to choose
- you need a working demo of favicon fingerprinting for research or education
- you want to test privacy tools against favicon-based tracking
- you are writing about or teaching browser fingerprinting techniques
When to avoid
- you want a production tracking system for real users - this is for demonstration only
- you need a privacy-respecting analytics solution
- you need general browser fingerprinting protection rather than a demo of the attack
