Bookmark Cleaner - Find and delete dead bookmarks in one click

How many of your bookmarks still work? Probably fewer than you think. Bookmark Cleaner scans every bookmark in your browser, detects dead links — 404s, timeouts, server errors — and lets you review and delete them in bulk. One-click scan of your entire bookmark library Review dead links before deleting — nothing is removed without your approval Zero data collection. Nothing leaves your browser. Ever. Lightweight. Vanilla JS. No frameworks, no bloat. Free and open source.

Hey Product Hunt! I built Bookmark Cleaner because I had 400+ bookmarks and suspected half of them were dead — old blogs, shut-down startups, expired domains. I was right. Existing tools were either bloated, wanted unnecessary permissions, or phoned home with my browsing data. I just needed something that checks URLs and lets me delete the broken ones. That's it. So I built exactly that: Click "Find dead bookmarks" Extension sends HEAD requests to every URL You see a checklist of broken links Uncheck anything you want to keep, delete the rest No accounts. No analytics. No background processes. Only runs when you click it. It's completely free and open source. I'd love your feedback — especially if you find false positives or edge cases I missed. Try it out and let me know how many dead bookmarks were hiding in your collection!
