Tab Zen

Automatically suspend or close inactive tabs on a schedule to free up memory, optimize browser performance, and speed up browsing.

When you have dozens of tabs open, your browser can consume a huge amount of memory, increase CPU load, overheat your device, make the fan spin loudly, and cause lag — making your computer sluggish and unresponsive. Tab Zen is designed to solve exactly this problem. It runs in the background, detects tabs that have been idle for too long, and then either suspends or closes them. This frees up memory and CPU resources, bringing your browser back to a smooth state. At the same time, it reduces distractions, helping you stay focused on what matters. The core philosophy behind Tab Zen is “automation with control” — striking a balance between performance and convenience: — Scheduled idle tab detection: Automatically detects tabs that haven’t been used for a set amount of time. — Two handling modes: — Close tabs: Fully remove the tab to save memory. — Suspend tabs: Put the tab to sleep but keep it in the tab bar without losing its content. — Smart exclusion: Customize a list of domains or URLs to exclude — so important sites like email or music players won’t be closed by mistake. — Auto—restore: When you click on a suspended tab, it automatically reloads and restores its original title. — Audio detection: Tabs playing audio or video won’t be mistakenly identified as idle.
