wBlock

What wBlock is

wBlock is a free, open-source ad blocker for Safari on Apple devices. It divides filtering among five Safari content blockers, with a stated capacity of 750,000 rules. It supports AdGuard-syntax lists, regional and annoyance lists, and custom lists added by URL, pasted text, or file. Users can control filtering, userscripts, and autoplay separately for individual sites, and use an element zapper. 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. iCloud can sync filter lists, custom filters, userscripts, the allowlist, and settings; users can also export a local backup. The privacy policy says wBlock has no built-in analytics or crash-reporting service and collects no browsing history, telemetry, or device identifiers. It is available through the App Store, Homebrew, and a downloadable DMG. Safari extensions must be enabled separately for Private Browsing, including all five blockers and wBlock Scripts.
