WebShield
A new wide-spectrum content blocker for Safari designed to be performant, efficient, and effective.
Project mention: WebShield – A new wide-spectrum content blocker for Safari | news.ycombinator.com | 2025-02-28To set a baseline: Ad blockers work by a combination of static rulesets and dynamic javascript.
Safari does not support the ruleset format of Chrome/Firefox, so a ruleset has to be maintained for it specifically. In practice this is always the AdGuard ruleset. I doubt a single adblocker doesn't use this as a base.
Beyond that is the custom JS they inject. It's hard to say how good it is but that is the only selling point:

AdGuard has its own too:
- https://github.com/AdguardTeam/AdGuardForSafari/tree/master/... (JS files)
They look similar in a lot of ways, because well they have to, but I haven't done any deep analysis.
Safari extensions will never match uBlock Origin because it simply does not provide the same APIs (webRequest blocking and DNS) that Firefox does.
