Page Keep Alive

Keep your web pages active and prevent them from going idle when you switch between windows
or tabs!

Page Keep-Alive is a powerful yet simple Chrome extension that prevents background
throttling, keeps pages active, and overrides visibility APIs to ensure your work is never
interrupted.

🎯 KEY FEATURES

• Per-Tab Control: Enable or disable keep-alive independently for each tab
• High Performance Mode: Aggressive timer overrides and visibility locking for complex apps
• Auto-Enable Sites: Automatically activate on specific URLs you configure
• Site-Specific Actions: Configure auto-click behaviors per hostname
• Visual Indicator: A clock display shows when keep-alive is active on a page
• Keyboard Shortcut: Toggle with Cmd+Shift+K (Mac) or Ctrl+Shift+K (Windows/Linux)
• Automatic State Persistence: Your settings are saved across browser restarts
• Lightweight & Efficient: Minimal resource usage with smart activity simulation
