Smart Suspender

Intelligently suspend inactive tabs to save memory with precise per-tab timing and keyboard shortcuts

Smart Suspender: Effortless Tab Suspension for a Faster, Lighter Browser Smart Suspender is a modern, privacy-focused Chrome extension designed to dramatically reduce your browser’s memory usage by intelligently suspending inactive tabs. Inspired by The Great Suspender but rebuilt from scratch with a focus on simplicity, reliability, and user control, Smart Suspender helps you keep dozens or even hundreds of tabs open without slowing down your computer. What does Smart Suspender do? Automatic Tab Suspension: Tabs that haven’t been used for a configurable period are automatically suspended, freeing up system memory and CPU resources. You can set the suspension interval to match your workflow, or disable auto-suspension entirely. Manual Controls: Instantly suspend the current tab, all tabs, or all other tabs with a single click from the popup or via customizable keyboard shortcuts. One-Click Restore: Suspended tabs can be restored instantly by clicking anywhere on the suspended page, pressing Space/Enter, or using the popup’s “Restore All Tabs” button. Intelligent Rules: Never suspend pinned tabs, tabs playing audio, or the active tab in each window—unless you want to. Easily whitelist specific sites or URLs using wildcards. Beautiful, Minimal UI: Enjoy a clean, modern popup and options page with clear controls and helpful feedback. The suspended page is ultra-lightweight for maximum memory savings. Privacy First: No analytics, no tracking, and no remote servers. All data is stored locally and only essential tab metadata is used for restoration.
