Blahker is a Safari content blocker designed to eliminate interstitial ads on Taiwanese websites. It is available as a Safari extension for both iOS and macOS, and its blocking rules are listed in a JSON file that can be updated without requiring an app update.
Blahker uses the WebKit API provided by Apple to block ads. When a user loads a webpage, Safari queries the Blahker extension for blocking rules, and the extension returns a JSON file containing the rules. This process ensures that user privacy is maintained, as the extension does not have access to the user's browsing history.
To install Blahker, users can download the iOS app from the App Store or the macOS extension from the GitHub repository. After installation, users need to enable the Blahker extension in Safari settings.
