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 suspends the tabs you're not using to free up RAM, so Chrome stays fast and your laptop stops overheating. Suspended tabs stay right where they are and reload instantly when you click them. You lose nothing. WHY DOZR IS DIFFERENT: IT NEVER LOSES YOUR TABS Most tab suspenders replace your page with their own placeholder, which is why people lose tabs after a restart, an update, or when they uninstall. Dozr uses Chrome's native suspension: your real URL is always kept, so your tabs can't vanish even if you remove Dozr. And it auto-saves your recent sessions as a safety net. FREE UP MEMORY - Auto-suspends tabs after they've been idle for a time you choose - Estimates each tab's memory and highlights the heaviest, so you spot the hogs at a glance - Suspend all inactive tabs in one click or wake any tab back up - Keeps pinned tabs, playing audio or video, and any site you allowlist wide awake - Keep any single tab awake with one click, without changing your settings NEVER LOSE A TAB - Save your open tabs as a session, then close them without losing anything - Auto-saved sessions and session recovery bring your window back after a crash - Reopen recently closed tabs with their history intact - Tab groups are restored exactly as they were, name and colour included - Close duplicate tabs in one click SHARE AND COLLAPSE - Collapse every open tab into a saved list with one click, freeing memory instantly - Share any saved session as a private link - The tabs are packed inside the link itself and decoded in the reader's browser, so nothing is ever uploaded to a server, and group names and colours are kept SNOOZE TABS FOR LATER - Right-click any tab to snooze it: it closes now and comes back when you choose - Quick presets (tonight, tomorrow, this weekend…) or an exact date and time BUILT TO FEEL RIGHT - Type to search, then use the arrow keys and Enter to jump straight to any tab - Light, dark, or automatic theme - Won't suspend a tab where you're typing, so your unsaved work stays safe - Keeps tabs awake while offline or on battery if you want - Keyboard shortcuts and a right-click menu for everything PRIVATE BY DESIGN - No accounts, no tracking, no ads - Dozr does not collect, store, or send any of your data, everything runs locally PERFECT FOR people who live with 20, 50 or 100+ tabs open, heavy users of AI chats, docs and design tools, and laptops that need every megabyte back. Available in English, Spanish, Portuguese, German, French, Italian, Indonesian and Japanese. Note: Chrome doesn't expose exact per-tab memory to extensions, so the figures shown are estimates based on documented averages. Install Dozr, keep the tabs you love, and let the rest take a nap.
