Adblock Fast review
A free, open-source blocker with broad browser coverage and a focused feature set.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Adblock Fast is a free, open-source ad-blocking product maintained by Rocketship. It is designed for people who want straightforward blocking across desktop and mobile browsers without a paid tier. The product blocks ads on Windows, in Chrome and Opera desktop browsers, in Samsung Internet on Android, and in Safari on iOS. Its core approach combines optimized filtering rules with CSS and JavaScript injection to hide ad elements on visited pages.
Its platform coverage is a central strength. Windows support includes blocking domains through DNS and Hosts-file changes, while mobile versions provide separate Fast and Faster blocking modes. The product also integrates with Samsung Internet, Safari, Chrome, and Opera, giving users several browser-specific paths. Blocking can be disabled for individual sites, and acceptable ads are not allowed. The Android version is specifically designed for Samsung Internet, while the iOS version works as a Safari content blocker, so the experience depends on the browser and operating system selected.
Adblock Fast keeps its scope narrow. It does not provide custom lists, element-picking controls, or cookie-popup controls, which may matter to users who want to tune filtering beyond the published ruleset. Opera support also has conflicting signals: the homepage documents it, while the repository marks Opera references as struck through, so availability may vary. Choose Adblock Fast for free, open-source, multi-browser blocking with simple controls. Choose an alternative if detailed filter customization, broader browser consistency, or cookie-popup handling is a priority.
