Anonymity checkers
BrowserSpy.dk
BrowserSpy.dk displays information a page can retrieve from a visitor’s browser through online tests. Its provider describes the results as diagnostics, not a complete security or anonymity assessment.
The tests may suit readers checking browser disclosures, provided they treat individual results as limited observations rather than an overall judgment.

Browser tests cover exposed information
The provider’s pages describe these checks, according to sources checked on 2026-10-31.
- Browser and operating-system information: details the site says visitors can inspect.
- Browser name, version, and reported capabilities: separate tests are listed.
- Network address: a test shows the address seen by the web server.
- Request information: visitors can inspect information their browser sends.
- Display properties: tests cover screen dimensions and color depth.
- Cookies: a test covers cookie behavior and cookies available to the site.
- Geolocation: the check uses the browser’s permission prompt.
Browser capabilities and system details
The capabilities list describes features supported by the client’s browser, rather than an overall privacy verdict. BrowserSpy.dk lists cookies, JavaScript, and HTTP headers among its capability tests.
Its result table includes entries such as ActiveXControls, Cookies, and JavaScript. The provider also says it reports browser details, installed fonts, and hardware information.
The FAQ groups its tests around browser details, privacy-related settings, and system capabilities. These reported properties describe what the browser or system exposes; they do not establish whether a user is anonymous.
Requests, permissions, and test results
A page visit is the mechanism: BrowserSpy.dk says it displays information retrievable from a visitor’s browser when visiting a page. The listed checks include request information and the network address seen by the web server.
The geolocation test uses the browser’s permission prompt, and precise location requires visitor permission. This makes permission relevant to interpreting that particular result.
The provider says results depend on the browser, device, and privacy protections in use. An unavailable value may mean a feature is unsupported, blocked, or restricted. The result alone therefore does not identify which explanation applies.
Free access to online tests
The provider states that BrowserSpy.dk is free to use, according to its homepage and FAQ checked on 2026-10-31.
The FAQ describes it as an online tool that cannot be downloaded. Access is therefore presented as browser-based, rather than as a downloadable application.
Resolution and GZip results need context
Before interpreting a resolution result, ask what the displayed measurements represent. The provider says the test reports the browser’s logical resolution and the display’s physical resolution.
The page defines DPI by the number of display pixels fitting within an inch and lists JavaScript as a detection method. It also displays logical resolution in inches and centimeters. A reader comparing results should establish which measurement is relevant to the question being asked.
For GZip, ask what the result indicates about the browser’s request. The provider says websites often use GZip to reduce data sent to a browser, commonly compressing CSS and JavaScript files.
The page says a browser can announce support through a GZip accept encoding header. Its result reports GZip support via gzip. Treat that as a reported capability, not a complete account of how a site delivers its files.
Named tests span browser and display data
- The listed checks include browser and operating-system information, request details, and the network address seen by a server.
- Separate tests cover browser name, version, and reported capabilities.
- Display checks report screen dimensions, color depth, and other display properties.
- Cookie behavior and cookies available to the site have a dedicated test.
- The geolocation test uses the browser permission prompt.
Diagnostic scope and legacy support limits
The provider says results vary with the visitor’s browser, device, and privacy protections. An unavailable value may reflect an unsupported, blocked, or restricted feature, leaving the result open to interpretation.
The tests are diagnostics, not a complete security or anonymity assessment, according to the provider. Historical tests for Flash, Java applets, and other plugins may be unavailable in modern browsers.
The FAQ lists verified support for Firefox 2 and 3 and Internet Explorer 6 and 7; it says supporting every browser across all tests is almost impossible. The FAQ also says a reported test error may not receive a fix because of limited time. Details still to check are listed under What we could not confirm.
Compare browser checks by scope
When comparing browser-check services, look at which browser disclosures they report and how they explain each result. Check whether they provide a comparison basis, how access is priced, and what limits they state. These criteria help distinguish a display of browser data from a broader assessment.
Useful for inspecting browser disclosures
BrowserSpy.dk may suit readers who want to inspect information a page can retrieve from a browser. Its listed scope also includes browser details, installed fonts, and hardware information.
That makes the service relevant for checking individual browser disclosures, not for treating a result as a complete anonymity or security judgment. Before relying on a result, identify which specific property it reports.
What we could not confirm

BrowserSpy.dk test questions answered
Does the geolocation test require permission?
The provider states that precise geolocation requires the visitor’s permission and that the test uses the browser’s permission prompt.
What can an unavailable test result mean?
The provider states that an unavailable value may indicate an unsupported, blocked, or restricted feature.
Do the tests provide a complete anonymity assessment?
No. The provider describes BrowserSpy.dk’s tests as diagnostics, not a complete security or anonymity assessment. The results depend on the visitor’s browser, device, and privacy protections. Use them as individual observations about retrievable information, not as an overall verdict.
Are historical plugin tests available in modern browsers?
Not necessarily: the provider says historical tests for Flash, Java applets, and other plugins may be unavailable in modern browsers. Its FAQ lists verified support for Firefox 2 and 3 and Internet Explorer 6 and 7, while noting that supporting all browsers across all tests is almost impossible.
Can BrowserSpy.dk be downloaded?
No. The provider describes BrowserSpy.dk as an online tool that cannot be downloaded. Its FAQ says the tool is free to use. The stated access model is online use rather than a downloadable application.
What information should an error report include?
The provider asks people reporting a test error to include their browser name and version, along with other relevant information. The FAQ directs users who cannot find an answer to contact the site through its contact page. It says a reported error may not receive a fix because of limited time.
Use the results as diagnostics
Fits if you want to inspect browser information retrievable by visiting a page. Probably not if you need a complete anonymity or security assessment. Main risk… treating a result as a definitive judgment despite the provider’s stated diagnostic scope. Check what each displayed result actually measures before relying on it.
