What it is

wBlock is a free, open-source ad blocker for Safari on Apple devices. It distributes filtering across five Safari content blockers, with a stated capacity of 750,000 rules. Users can add AdGuard-syntax, regional, annoyance, and custom filter lists by URL, pasted text, or file, and use an element zapper to remove page elements. Filtering, userscripts, and autoplay can be controlled separately for individual sites. The app includes a Greasemonkey-compatible userscript engine and supports UserCSS themes, including Less, Sass, and Stylus. Tube Cleaner and Player Cleaner add video options such as Picture-in-Picture and background audio. Its script catalog includes SponsorBlock, DeArrow, Dark Reader, Return YouTube Dislike, and TwitchAdSolutions. iCloud can sync lists, custom filters, userscripts, the allowlist, and settings; users can export a local backup instead. The privacy policy says the app does not collect browsing history, telemetry, or device identifiers and has no built-in analytics or crash reporting. It is available through the App Store, Homebrew, and a DMG download.

Strong points and limits

Strong points

  • Filtering capacity stated as 750,000 rules
  • Supports custom filter lists and element removal
  • Includes userscripts and UserCSS themes
  • Offers iCloud sync or local backup
  • Privacy policy says it collects no browsing history

Limits

  • Safari is the only listed browser
  • Private Browsing requires separately enabling extensions
  • No free trial is listed

Who it suits

wBlock suits Safari users on Apple devices who want extensive filter-list controls, userscripts, and video options. Users who browse privately should account for Safari's separate extension-enabling requirement.

Verdict

wBlock combines ad filtering with site-level controls, scripts, and Safari video features at no cost. Private Browsing requires an extra extension-enabling step for the blockers and scripts.
