The original
Webbkoll
A web-based privacy checker for cookies, third-party requests, HTTPS and security headers.
Replacements
Listings that take over the same core job as Webbkoll.
Blacklight
A real-time website privacy inspector that reveals the tracking technologies a site uses.
Blacklight focuses on tracking, detecting fingerprinting, session recording and keystroke capture, with location and device choice, but does not check security headers.
Cookiebot Cookie Checker
A free online scanner that finds and categorizes the cookies and trackers a website uses.
Cookiebot Cookie Checker categorizes cookies and third-party requests with a compliance risk assessment, but delivers its report by email and promotes a consent product.
Cookieserve
A free online cookie checker that scans a website and reports the cookies it sets.
Cookieserve gives an instant cookie report without sign-up, but covers cookies rather than every tracker, HTTPS or headers, and promotes a consent product.
CookieYes Cookie Checker
A free online tool that scans a website and lists every cookie it sets by category.
CookieYes Cookie Checker lists cookies by category within seconds, but ignores other third-party requests and security headers and leads into a paid consent product.
