Find and close duplicate tabs instantly, even with 500+ tabs open. No lag, no content scripts, no browsing history access. Stop losing time to duplicate tabs. TabTidy finds tabs you've accidentally opened twice — the same article, the same inbox, the same product page — and closes them with one click. Built for people who keep dozens, or hundreds, of tabs open at once. Built to stay fast, no matter how many tabs you have Most tab-cleanup tools re-scan every open tab every time something changes, so they get slower the more tabs you have. TabTidy keeps a lightweight running index instead, updating only the tab that actually changed — detection stays instant whether you have 10 tabs or 500. In testing, 450 lightweight tabs used about a quarter of the memory that just 33 heavy tabs (video, complex web apps) did — tab count was never really the problem. What TabTidy does Detects duplicate tabs by URL, with smart matching for www / trailing-slash / anchor differences One-click close, with control over which tab to keep Exclude specific URLs you never want flagged — not just whole domains Tab-group aware — won't flag tabs you deliberately opened side-by-side to compare TabTidy Pro (one-time purchase, no subscription) Live toolbar badge — see your duplicate count at a glance, updated in real time, no need to click to check Cross-window detection — catches duplicates across all your open windows, not just the current one Smart link matching — recognizes duplicates even when links carry different tracking parameters (utm_*, fbclid, gclid…), like when the same article gets shared through different channels Custom close rules — keep pinned tabs first, or your most recently active tab Settings sync across your devices Privacy by design TabTidy only reads tab URLs and titles — the minimum needed to detect duplicates. It never injects scripts into your pages, never reads your browsing history, and never sends your tab data anywhere. Everything happens locally in your browser. Free vs Pro The free version handles manual scanning and cleanup for your current window — genuinely useful on its own, with no artificial limits on how many duplicates you can close or exclude. Pro adds automatic, always-on monitoring and smarter matching for people managing tabs across multiple windows all day.
