Ads stop before they load
Our Manifest V3 engine filters ad requests at the source using Chrome's nativedeclarativeNetRequest — ad servers never even get the hit, so nothing flashes in and pulls the page around.
🕵️
Trackers don't get a vote
Analytics beacons and third-party trackers are blocked alongside display ads, so companies can't quietly build a profile from everywhere you go.

Faster, lighter, calmer
Fewer requests and zero ad scripts mean pages render quicker, scroll smoother, and use less data and battery — on every browser you already use.
One price. No catch.
