BrowserScan
Check browser fingerprints and run DNS leak, IP, port, and WebRTC tests with BrowserScan.
About BrowserScan
BrowserScan is a web-based set of tools that shows what a website can learn about a visitor's browser, device, and internet connection. Its main page reports the visitor's IP address, approximate location, ISP, proxy status, and a range of browser fingerprint values, such as canvas, WebGL, audio, screen, and language settings.
Its tests include DNS leak, WebRTC leak, port scanning, user agent parsing, and an HTTP2/SSL/TLS check. The site describes these checks as a way to improve online privacy. The port scanner only checks ports 22 and 3389, according to the page. Results reflect the browser and connection used on the day of the test, and the page does not state how long any data is kept or whether it is shared.
