RAM Manager

Suspend idle tabs to free memory. Lightweight, fast, and themeable.

RAM Manager suspends idle tabs to free up memory and keep Google Chrome running fast. This extension is perfect for tab hoarders, researchers, and anyone who keeps dozens of tabs open. Compared to other extensions, this one is kept as light as possible. RAM Manager doesn't close tabs — it "suspends" them, so you can restore instantly, right where you left off, with a shortcut or a button. FEATURES • Auto Suspend — automatically freeze tabs after a period of inactivity (timer length is yours to set) • Instant Restore — bring a tab back with one click or the Alt+Shift+X keyboard shortcut (customizable) • Auto Restore — optionally wake suspended tabs automatically when you switch to them • Smart Protection — never suspends tabs playing audio, pinned tabs, or your active tab; internal pages, localhost, and private-network addresses are always left alone • Whitelist — keep important sites always awake • 28 Themes — light, dark, and system modes, plus custom CSS snippets to make every page yours • Sessions — save a window's tabs and restore it later, close duplicate tabs, or export your tab list to the clipboard • Stats Dashboard — see memory saved today and all time, weekly charts, and your heaviest sites at a glance • Suspend on Minimize — optionally put an entire window's tabs to sleep when you switch away • Toolbar Badge — keep an eye on how many tabs are sleeping • Lightweight & Private — no tracking, no external calls, minimal permissions; everything stays on your device HOW IT WORKS Suspended tabs navigate to a lightweight local page that stores your original URL. When you're ready, restore the tab with one click or your keyboard shortcut — the page reloads fresh, right where you left off. Your browsing history and data remain untouched, and your settings, whitelist, and stats can be exported or imported anytime.
