TabNap puts idle tabs to sleep the moment your computer's memory actually needs it back — and wakes them up automatically once it recovers. Nothing closes for good. Every MB saved is measured, not estimated.
Not just another tab organizer — TabNap watches your computer's real memory pressure and acts on it.
TabNap watches your computer's actual free RAM, not a fixed timer — it acts when memory is genuinely tight, and backs off once it recovers.
Every MB of savings shown is a real before/after reading of your system's free memory — never a guess or a per-tab estimate.
Tabs playing audio or in a call are automatically protected, every time — plus a Never Sleep list for anything else you add yourself.
A sleeping tab is still there — title, favicon, scroll position — and wakes up the instant you click back to it.
Automatic sleeping and protection are free, forever. Pro adds finer control for power users.
