Tab Sleeper Pro — Suspend Tabs & Save Memory

Tab Sleeper Pro suspends inactive tabs to free up memory and speed up your browser, then wakes them with one click.

Too many open tabs slow your browser down and eat your computer's memory. Tab Sleeper fixes that quietly in the background. When a tab sits unused for a while, Tab Sleeper puts it to sleep — replacing it with a lightweight placeholder and freeing the memory that tab was holding. The moment you click it (or press Enter), your page loads right back, exactly where it was. You keep all your tabs; your browser just stops choking on them. WHY YOU'LL LIKE IT Frees up RAM automatically, so Chrome stays fast and responsive One click — or the Enter key — brings any sleeping tab back instantly You choose how long a tab can sit idle before it sleeps (1 minute to 2 hours, or manual-only) Snooze the current tab, snooze everything else, or wake all tabs from one menu SMART BY DEFAULT Never sleeps the tab you're actively looking at Leaves pinned tabs alone (optional) Leaves tabs that are playing audio or video alone (optional) Keep favorite sites awake forever with a simple allow-list PRIVATE BY DESIGN Tab Sleeper does not collect, transmit, or sell any data. Your settings live on your own device, nothing is sent anywhere, and there's no tracking, no analytics, and no remote code. It only asks for the permissions it genuinely needs to suspend and restore tabs. Install Tab Sleeper, set your snooze timer, and let your browser breathe again.
