BannerSlayer — Block App Download Popups geliştiren: Swalter Factories

BannerSlayer instantly destroys "Open in App" popups, smart app banners, and interstitial overlays the moment they appear — on Reddit, YouTube, Pinterest, LinkedIn, and every other site that won't stop pestering you to download their app.
What it blocks:
Every major form of app-push dark pattern is covered. Native iOS and Android smart banners (triggered by hidden meta tags in the page's HTML) are removed before they ever render. Fixed-position "Open in App" overlays that darken the page and block your content are nuked on detection. Scroll-lock overlays that freeze the page behind a modal are removed and your scroll is restored automatically. Dynamically injected banners — the kind Reddit fires after you click a post — are caught by a real-time DOM watcher and eliminated the moment they appear, not after you've already seen them.
How it works:
Three detection layers work simultaneously. First, <meta name="apple-itunes-app"> and <meta name="google-play-app"> tags are stripped from the page before the browser renders them. Second, a list of known CSS selectors targets platform-specific banner components on Reddit, YouTube, Pinterest, LinkedIn, Twitter/X, Instagram, TikTok, Yelp, Quora, Medium, and more. Third, a heuristic scanner catches unknown banners on sites not in the list — if a fixed-position element spanning the full viewport contains text like "Open in App," "Get the App," or "Use Our App," it gets removed regardless of which site you're on.
Your privacy:
Zero data ever leaves your browser. BannerSlayer collects nothing, transmits nothing, and has no server. All stats are stored locally on your device.
Kill counter:
The popup tracks every banner blocked — lifetime total, today's count, and a per-site breakdown showing which sites tried to push their app on you most aggressively. Share your kill count.
