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.
Free for 7 days, then $2.99/mo to keep blocking. Cancel anytime, in two clicks.
