Idle tabs dim, doze off and hand back their memory, keeping their place.
Pick your trade-off
A featherweight placeholder keeps the title and favicon, and wakes instantly when you return.
Both modes are one toggle apart in settings.
Stop paying rent for tabs you're not reading.
Browsers keep every tab loaded forever - a suspender lets you hoard them anyway.
Without a suspender
- Every open tab keeps its full page in memory, even from last week.
- Tab memory piles into gigabytes: fans spin, the battery drains, switching lags.
- The only fix is closing tabs - and losing your place.
With InTab
- Tabs idle for 30 quiet minutes go to sleep, on your schedule.
- Their memory goes back to the tabs and apps you're actually using.
- Every tab keeps its spot, title and favicon - nothing to re-find.
It watches the clock so you don't.
InTab watches idle time
A once-a-minute check tracks each tab's idle time - your active tab never counts.
Quiet tabs doze off
After 30 idle minutes (your setting) a tab suspends - title gets a 💤, favicon stays.
Anything wakes them
Click, press a key, or switch to it - it restores instantly, parked never closed.
Tuned for how you actually browse.
Sleep or Hibernate
Sleep parks the page for instant wake; Hibernate frees all RAM and reloads on return.
Minutes to weeks
Suspend after anywhere from 5 minutes to 3 weeks - default is 30 minutes.
Protected sites
Keep domains, wildcards or URL patterns permanently awake - matching tabs never sleep.
One-click sweeps
Suspend every other tab or a whole window in one click - restore just as fast.
It knows when not to sleep.
Nine guardrails ship by default - every one is yours to change.
100% local, by design.
Suspension runs entirely inside your browser - even the unsaved-form check. InTab never tracks URLs, page content, or what you type.

Before you ask
No. Before suspending, InTab checks the tab for unsaved text in forms and editors and skips it if anything is found - that guard ships on by default. Tabs playing audio, pinned tabs and your active tab are never suspended either.
Give your laptop its RAM back.
Ships free with 15+ other tools: AI writing, tab sessions, screenshots, focus sounds and more.
