What wBlock is

wBlock is a free, open-source ad blocker for Safari on Apple devices. Its filtering is divided among 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. An element zapper can remove individual page elements, while filtering, userscripts, and autoplay can be controlled separately for each site. wBlock includes a Greasemonkey-compatible userscript engine and supports UserCSS themes, including Less, Sass, and Stylus. Tube Cleaner and Player Cleaner add Safari video features such as Picture-in-Picture and background audio. Its script catalog lists SponsorBlock, DeArrow, Dark Reader, Return YouTube Dislike, and TwitchAdSolutions. iCloud can sync filter lists, custom filters, scripts, allowlist, and settings; users can export a local backup instead. The privacy policy says it has no built-in analytics or crash reporting and does not collect browsing history, telemetry, or device identifiers. It is available through the App Store, Homebrew, or a DMG download.
