TabLens

TabLens finds any tab instantly and makes sure you never open a duplicate again. ⚡ NEVER OPEN THE SAME TAB TWICE TabLens watches every tab you open in real time. The moment a duplicate URL appears, it shows a notification with two choices: • Continue — stay where you are, the new tab closes quietly. • Take me to the existing tab — jump straight to the original. Duplicate detection works across all windows. It normalises URLs first, so tracking parameters (utm_*, fbclid, gclid, etc.) and trailing slashes don't trick it — while pages that are genuinely different are never mistaken for duplicates. 🧹 CLEAN UP IN ONE CLICK Already drowning in duplicates? TabLens counts them the moment you open it and offers a one-click sweep. Pinned tabs are always safe. 🔍 FIND ANY TAB INSTANTLY Type a few letters and TabLens filters every open tab across all your windows — smart fuzzy matching forgives typos and partial words. Press Alt+M anywhere in Chrome to open TabLens with the search bar focused, or press / inside the popup. 🗂 WINDOW BASICS DONE RIGHT • Rename any browser window so you always know which workspace is which. • Merge all windows into one with a single click. ✅ NO ACCOUNT. NO CLOUD. NO SUBSCRIPTION. Your tabs stay on your machine. TabLens requests no host permissions — it cannot read or change the pages you visit. It never phones home, never injects scripts, and never tracks your browsing history. This is version 1.0, deliberately focused on doing two things perfectly: search and duplicate protection. Saved tabs, sessions, tags, and automation rules are on the roadmap and will arrive as free updates.
