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.

What it tests

• 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.

Host lists

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.
