RAMGuard

RAMGuard automatically hibernates inactive tabs after 1 minute — keeps Chrome, Brave, Edge, Opera, Vivaldi fast. 100% free.

RAMGuard automatically puts your inactive tabs to sleep after 1 minute. It solves the most common Chrome problem: too many open tabs eating all your RAM, making the browser slow, hot, and laggy. Once installed, RAMGuard quietly watches your tabs in the background. Any tab you haven't used for 1 minute is automatically hibernated — freeing up memory instantly while keeping the tab exactly as you left it. When you click on a sleeping tab, it wakes up immediately. Why users love it: • Dramatically reduces RAM usage (often 50-80% less) • Stops browser lag and fan noise • One-click "Hibernate Inactive Now" button • Global hotkey (Ctrl + Shift + H) for instant relief • Shows you exactly how much RAM you've saved • Clean, modern UI with dark and light mode Perfect for developers, researchers, students, and anyone who regularly has 20+ tabs open. 100% free. No account. No tracking. No bloat. Just works.
