Which browser has a built-in ad blocker?

Browsers like Brave, Opera, or Vivaldi promise to block all ads by default. However, their built-in filters are often rigid, consume significant system resources, or whitelist their own commercial partners' ads.

The perimeter filtering alternative

Even if a browser includes a native ad blocker, it often lacks the flexibility of a dedicated extension. AdBlock Network operates externally and independently. To update its rule sets, the software performs read-only asynchronous requests to multiple independent endpoints to power the firewall, utilizing the Address layer for cleaner ad-blocking.
