AdBlockTest

A small, privacy-first ad blocker test. See if your blocker, DNS filter, or VPN catches ads, trackers, and analytics.

Hi, I'm TurtleCute, and I love testing my adblocker. I cleaned, modernized, and debloated d3ward's original project to keep the test online.

• Hosts: ads, analytics, trackers, social, and OEM domains.
• Cosmetic filters: whether ad-shaped DOM elements get hidden.
• Script blocking: whether ads.js and pagead.js style scripts load.

Two formats if your blocker isn't catching enough. Subscribe to these URLs:

• d3host.txt (hosts file) — covers the Host category only. A hosts file cannot pass the cosmetic filter or ad script checks, so pair it with a browser extension for a full score.
• d3host.adblock (adblock syntax) — covers every category, because it also carries the cosmetic and script rules.

The list ships with Blokada and the OISD List.

Requires Node.js 22.15 or newer.

npm install
npm run dev      # webpack dev server
npm run build    # production build to /dist
