Dozr – Suspend Tabs & Save Memory

Suspend inactive tabs to free up RAM and speed up Chrome. See what uses memory; keep important tabs awake. No ads or tracking.

Too many tabs slowing Chrome to a crawl? Every open tab quietly eats memory, even the ones you haven't touched in hours. Dozr fixes that. Dozr automatically suspends inactive tabs to free up RAM, so Chrome stays fast and your laptop stops overheating. Suspended tabs stay right where they are in your tab bar and reload instantly when you click them, you lose nothing. WHY DOZR IS DIFFERENT: NEVER LOSES YOUR TABS Most tab suspenders replace your page with their own placeholder page, which is why people lose tabs after a restart, an update, or when they uninstall. Dozr uses Chrome's native suspension instead: your real URL is always kept, so your tabs can't vanish, even if you remove Dozr. On top of that, Dozr auto-saves your recent sessions as a safety net. WHAT DOZR DOES - Auto-suspends tabs after they've been idle for a time you choose - Frees the memory those background tabs were wasting - Shows your tabs in five clear views: Active, Inactive, Suspended, Sessions and Scheduled - Estimates how much memory each tab is using, so you can spot the heavy ones - One click to suspend all inactive tabs or wake any tab back up - Keyboard shortcuts and a right-click menu for fast suspending - Global search across every tab and saved session, so you find anything instantly SNOOZE TABS FOR LATER - Right-click any tab and snooze it: it closes now and comes back automatically at the time you pick - Quick presets (later today, tonight, tomorrow, this weekend, next week) or an exact date and time - A "Scheduled" view shows everything waiting to return; open any one early or cancel it - Snoozed tabs are stored locally, so you never lose the page SESSIONS THAT PROTECT YOU - Auto-saves your last few sessions automatically, so a closed window is always recoverable - Save your open tabs as a named session, then close them without losing anything - Preview a session's tabs and reopen just one, a few, or all of them - Keeps your tab groups intact when you save and restore a session - Pick exactly what to save: whole groups of tabs, or individual ones - Sessions are stored on your device only, never uploaded anywhere NEVER LOSE UNSAVED WORK - Dozr won't suspend a tab where you have unsaved text in a form or editor - Your work in progress stays safe, even while everything else sleeps YOU'RE IN CONTROL - Never suspends the tab you're using - Keeps pinned tabs awake - Keeps tabs playing audio or video awake (no interrupted music or calls) - Allowlist any site that should never sleep (e.g. your AI chat or email) - Right-click any page to keep that site awake for good - Set your own idle time and check interval PRIVATE BY DESIGN - No accounts, no tracking, no ads - Dozr does not collect, store, or send any of your data - Everything runs locally in your browser PERFECT FOR - People who live with 20, 50 or 100+ tabs open - Heavy users of AI chats, Google Docs, Figma and other memory-hungry sites - Laptops with 8 GB of RAM that need every megabyte back Available in English, Spanish and Portuguese. Note: exact per-tab memory isn't exposed to extensions by Chrome, so the figures shown are estimates based on documented averages. For precise numbers, Chrome's own Task Manager (Shift+Esc) is one click away. Install Dozr, keep the tabs you love, and let the rest take a nap.
