Know what websites see
How browser detection works
Browsers share a limited set of details so websites can render correctly, choose compatible features and troubleshoot problems. The same combination can also contribute to browser fingerprinting.
Local analysis
Browser and privacy checks run in this tab. The local signal digest is displayed to you and is not uploaded or stored.
Optional edge lookup
Your public IP is already visible to any website you visit. Our Cloudflare endpoint enriches it with network and location context.
Is this browser checker accurate?
It uses modern client hints when available and falls back to the user-agent string. Some privacy-focused browsers intentionally reduce or disguise version and hardware details, so those fields are labeled as unavailable rather than guessed.
Does this site save my fingerprint?
No. The browser checks and local digest run in your browser. This production version includes no analytics, advertising scripts or fingerprint database.
Why does a website need my browser version?
Version information helps sites select compatible code, diagnose rendering problems and explain why a feature may be unavailable.
Can this tell whether I use a VPN?
The network layer can surface proxy, VPN or datacenter indicators when the IP intelligence source provides them. These are probabilistic signals, not definitive proof.
