Less noise. More page.
A focused set of Safari rules reduces common ads and trackers while letting the content you came for stay in view.
Hide familiar ad slots
Two cosmetic rules hide selected ad placements and site-specific clutter.
Built into Safari
WebKit compiles the rules and applies them in the browser. The companion app checks status and reloads filters.
No browsing-history access.
SadeBlock does not read your history, log requests, run telemetry, or send browsing data to a server.
The rules are bundled with the app and can be inspected in the open-source repository.Install in Safari
SadeBlock is currently available as an open-source Xcode project for macOS 13 or later.
Open the project
Download or clone the repository, then open SadeBlock.xcodeproj in Xcode.
Build for your Mac
Choose the SadeBlock scheme and My Mac, then run the app. For a signed build, configure your Apple development team for both targets.
Enable the blocker
Open Safari Settings → Extensions, enable SadeBlock, then refresh your tabs. Local unsigned builds may need Safari’s developer setting.
Need more detail? Read the installation guide. This early version uses a small, manually maintained ruleset; first-party and in-video ads may remain.
