How these tests work
Browser and fingerprint hashes are calculated in this page. Network metadata comes from the request already handled by BrowserCheck's Cloudflare deployment. The WebRTC comparison uses a STUN request. DNS leaks, blacklist reputation, proxy/VPN status, Tor use, open ports, malware and extension safety are not tested here.
Antidetect browser directory & comparisons

Frequently asked questions
What is a browser fingerprint?
A browser fingerprint is a combination of browser-exposed attributes such as the user agent, screen size, language, timezone and rendering outputs. A single value rarely identifies someone by itself; combinations can help sites recognize repeat environments.
Does this page prove that my browser is secure?
No. It reports selected browser and network signals. It does not scan for malware, vulnerable extensions, missing security patches, compromised accounts or unsafe website content.
Does a matching WebRTC and request IP prove there is no leak?
No. It means this session exposed no different public address through the WebRTC check. DNS traffic, VPN routing, IPv6 behavior and other applications require separate tests.
How can I reduce fingerprint exposure?
Keep the browser updated, prefer built-in privacy protections, limit unnecessary extensions, and avoid making many unusual one-off changes. Tor Browser offers stronger fingerprint standardization when its defaults are kept intact.
