🌟 Why Bookmark Manager Zero?
Stop blindly clicking old bookmarks. Know which links are dead, parked, or potentially dangerous before you visit them.
Other bookmark managers make you choose between organization OR security. Bookmark Manager Zero combines both with:
🔗 Intelligent Link Detection
- Dead Link Detection - Automatically identifies broken URLs (404s, server errors)
- Parked Domain Detection - Spots expired domains redirecting to parking pages (22+ parking services)
- HTTP Redirect Detection - Detects when HTTP bookmarks redirect to HTTPS
- Visual Status Icons - Instant visual feedback with clickable chain icons showing detailed status
