1Blocker vs uBlock Origin Lite

1Blocker is an ad and content blocker for Apple devices, with Safari filtering, custom rules and options for tracker and cookie-popup blocking. Its Safari content blocker filters ads, cookie banners, annoyances and trackers; the separate 1Blocker Scripts extension targets harder-to-block ads and annoyances, including YouTube video ads. On iOS, an in-app tracking filter uses a local VPN profile to block invisible trackers across apps. 1Blocker says filtering happens locally and that the app does not collect personal information or track visited sites. Listed platforms are iOS, macOS and browser extension, with visionOS also supported. Requirements are iOS 16.0 or later and macOS 13.0 Ventura or later. Free mode permits one blocking filter at a time and custom rules. A 14-day trial is listed. Paid options are $2.99 a month, $14.99 a year and a lifetime plan listed at $39.99 a month, described as a one-time payment. Premium includes multiple categories, filter updates and in-app tracker protection.

uBlock Origin Lite is a free, open-source content-blocking extension built on the Manifest V3 API. It blocks ads, trackers, miners, and other content after installation. Its default rules include uBlock Origin lists, EasyList, EasyPrivacy, and Peter Lowe’s ad and tracking server list. Users can add rulesets, custom filters, and filter lists, and use an element picker and cookie-popup blocking. Filtering is declarative, so no permanent process is required; the project says the browser performs CSS and JavaScript injection and the extension itself uses no CPU or memory while blocking. The project says it collects no data, has no analytics or telemetry hooks, and makes no remote requests except for filter lists users explicitly subscribe to. Users can allow all-site filtering or reduce host permissions. It warns Lite is not an automatic uBlock Origin replacement and may be less effective against anti-blocker sites or breakage.
