Ka-Block! is a content blocker for Safari that prevents ads and tracking scripts from slowing down web pages you visit.

Many sites use third-party scripts to track your behavior across the web, causing pages to load slowly and draining your Mac’s battery. Blocking these scripts dramatically improves page load time, data usage, and battery life.

- Fast, curated filter list

- Also available for Safari on iPhone

Protecting privacy and performance on the web is important. We hope you enjoy Ka-Block!
