Your browser tries to reach known ad, tracking, and malicious domains across seven categories. If your DNS blocks them, they fail. See exactly what is and is not getting through.
Works with AdGuard Home, Pi-hole, NextDNS, Cloudflare, and Harbor Privacy. Runs entirely in your browser -- no data leaves your device, nothing is logged.
How it works: your browser tries to open a network connection to each domain. If DNS blocks it, the connection never happens -- that is a pass. Domains span major ad networks, trackers, social widgets, video ad platforms, malware and phishing infrastructure, cryptomining scripts, and adult content -- the same categories AdGuard Home, Pi-hole, and NextDNS filter by default. Results are never sent anywhere.
