BrowserLeaks is a suite of browser-based tools that test browser security and privacy. The tests identify ways websites may reveal a real IP address, collect device information and perform browser fingerprinting. Tools include IP address display, reverse IP lookup, HTTP header, country, ISP and local time checks, plus WebRTC, DNS and IPv6 leak tests. A Features Detection tool lists HTML5 feature support.
PopUpOFF is a non-commercial, open-source browser extension that removes popups, overlays and cookie notifications. It offers aggressive, moderate and delicate modes, plus an experimental Anti-paid feature. Information is stored locally and the project states it uses no tracking or analytics.
Webbkoll is a service that checks which data-protecting measures a site has taken to help users exercise control over their privacy. It is run by the 5th of July Foundation in Sweden. The tool simulates a normal browser visit with Do Not Track disabled and no add-ons, and http:// is checked even when https:// is entered.
AnonymousRedirect helps block ads, trackers, sponsored segments, popups, or unwanted web content.
Cover Your Tracks is a project of the Electronic Frontier Foundation that tests a browser to show how well it is protected from tracking and fingerprinting. It shows how trackers view the browser and gives an overview of the browser's most unique and identifying characteristics. Only anonymous data is collected through the site.
A browser fingerprinting test page that reports a range of signals, including timezone, Intl data, headless-browser and stealth percentages, WebRTC connection details, WebGL, screen properties, canvas, audio, fonts, speech and media information. It also lists JS/DOM, CSS and window feature results and provides a test interface with sections for workers, iframes, fonts, timezone and extensions.
Blacklight is a real-time website privacy inspector from The Markup. A user enters a website address and Blacklight scans it, revealing user-tracking technologies on the site. Tests cover ad trackers, third-party cookies, tracking that evades cookie blockers, session-monitoring scripts, keystroke capturing, and data sent to Facebook, TikTok, Twitter/X and Google Analytics. A scan normally takes between 30 seconds and one minute.
