Everything CatBlock blocks
One lightweight extension that clears the clutter, protects your privacy, and speeds up every page.
Display & video ads
Banners, interstitials, and video pre-, mid-, and post-rolls are stopped before they load.
Pop-ups & overlays
Newsletter pop-ups, floating overlays, and “subscribe” nags never get in your way.
Trackers & beacons
Third-party analytics and tracking pixels are blocked so your browsing stays yours.
Cookie-consent nags
Hide the endless cookie banners on popular sites for a cleaner first impression.
Faster page loads
Fewer requests and no ad scripts mean pages render quicker and use less data and battery.
Private by design
Your browsing never leaves your device. CatBlock only talks to our licensing API.
Native MV3 engine
Built on Chrome’s declarativeNetRequest: fast, efficient, and future-proof.
Auto-updating filters
Filter rules refresh automatically so you stay protected as the web changes.
Every major browser
Chrome, Edge, Opera, and Brave. One blocker, everywhere you browse.
