Adblock Fast vs AdGuard

Adblock Fast is a free ad blocker for desktop computers and mobile browsers. It uses 12 optimized filtering rules derived from EasyList and Bluhell Firewall; the maker says these rules are intended to speed page loading while using less CPU, memory and storage. On Android it blocks ads in Samsung Internet 4.0 and later, and on iOS it works in Safari. The maker lists support for Windows 7 and later and a Chrome desktop extension; the repository marks Opera support as discontinued. In Chrome, the toolbar button can disable blocking for a site, and the choice is remembered when a user returns. Mobile users can choose the default Fast rules or an experimental Faster mode with more comprehensive, current rules. The maker says Faster mode anonymously crawls common websites using background bandwidth without cookies or other personal information. The blocker intercepts HTTP traffic and injects CSS and JavaScript into visited pages to block requests and hide ad elements. Its code is open source under the GNU General Public License version 3 or later, subject to listed exceptions. The app does not block ads in other Android or iOS apps.

AdGuard is a family of apps and services for filtering content across desktop and mobile devices. Its tools include custom filter lists, an element picker and cookie-popup blocking. The listed apps cover Windows, Mac, Android, Android TV, iOS, browsers and Linux, while AdGuard Home can extend coverage across a home network when installed on a router. Security features block phishing, malware, dangerous and malicious sites, and inappropriate content. AdGuard Content Blocker and AdGuard DNS are free products; Content Blocker works in Samsung Internet and Yandex Browser, with fewer features than the Android version. Personal licenses cover three devices and Family licenses cover nine. Licenses are available for one year or a lifetime, with annual billing or a one-time payment, but no prices are listed. Trials last 14 days for Windows, Mac, Android and Android TV, and seven days for iOS Premium. Purchases have a 30-day money-back guarantee for requests within 30 days. Support is available by email 24/7.
