Drowzy - Tab Suspender & Memory Saver

Too many tabs dragging Chrome down? Drowzy is a lightweight tab suspender and memory saver that puts the tabs you're not using to sleep, freeing up the memory they were holding (up to 80% per tab) so your browser stays fast and responsive no matter how many tabs you keep open.

Unlike older tab suspenders, Drowzy uses Chrome's built-in discard. Your tabs are never replaced with a custom page and never lost. Even if you uninstall Drowzy, every tab is still exactly where you left it.

▸ HOW IT WORKS
• Tabs you haven't touched in 15 minutes suspend automatically (the timer is fully configurable, from a few minutes to a few hours, or never).
• Suspended tabs free up most of their memory but stay right in your tab bar.
• Click any suspended tab to wake it instantly, exactly where you left off.

▸ SMART PROTECTION (your important tabs are never touched)
• The tab you're actively using
• Pinned tabs and tabs playing audio
• Tabs with unsaved form input
• Any site you add to your whitelist

▸ FEATURES
• Save and restore whole windows of tabs as named sessions, and export them as JSON for a backup
• One-click "Suspend Others" and "Wake All"
• Keyboard shortcuts: Alt+S (suspend current), Alt+Shift+S (suspend others), Alt+W (wake all)
• Right-click menu for quick suspend and whitelist
• Lifetime stats: see how much memory you've saved, today and all-time
• Dark and light themes
• Settings that sync across your devices
• Available in 50+ languages, with full right-to-left support

▸ PRIVATE BY DESIGN
• Zero data collection and zero tracking
• No accounts, no analytics, no external servers
• Everything stays on your device, saved with Chrome's own storage
• Fully open source, so anyone can verify exactly what it does

Perfect for researchers, developers, writers, students, and anyone who lives with dozens of tabs open. Install Drowzy, open it from your toolbar, hit "Suspend Others," and watch your memory free up.
