AdGuard vs Ka-Block!

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.

Ka-Block! is a free Safari browser extension for blocking a curated selection of advertisements and trackers. It is available as an extension and on iOS and macOS, covering desktop and mobile devices while supporting only Safari. The project says blocking third-party scripts can reduce page-load time, data use and battery drain. Its filtering code makes zero network connections, and the extension does not access pages loaded by the browser. Apple’s listing reports that the developer says the app collects no data. Ka-Block! aims to block most ads and trackers without slowing pages, while acknowledging that some advertisements may remain. The blocked-domain list changes only when a new extension version is released, and custom filter lists are not supported. The project is open source under the MIT license. The listed plans cost nothing. iOS requires version 12.0 or later, and the listed App Store version is 3.5 from November 6, 2021.
