Is Tab Nap a Great Suspender alternative?

Yes. Tab Nap auto-suspends idle tabs on modern Manifest V3 Chrome using the official discard API — the safe successor spirit of The Great Suspender, not affiliated with the original project.

Does Tab Nap free RAM?

Yes. Idle tabs past your timer are discarded with Chrome’s native API so memory can return without freeze hacks.

Can I whitelist sites?

Yes. Add hosts that should never nap (e.g. mail). Pinned and audible tabs are protected by default.

Tabs That Actually Nap

Scroll — see the RAM come back

But what does it actually do?

Tab Nap is a free Great Suspender alternative: auto-suspend idle tabs with Chrome's native discard API — free RAM without freeze hacks.

Tab suspender for Manifest V3. Modern Chrome.

Sleep the noise. Keep the work.

Idle tabs nap. Active tabs stay awake.

Whitelist mail and docs. Never suspend pinned or audio. Wake everything in one click when you need the circus back.

What Tab Nap does for you

Auto-suspend

Tabs idle past your timer are discarded with Chrome's official API — safe, supported, no frozen zombies.

Smart exceptions

Pinned, audible, active, and your host whitelist never nap. Gmail can stay awake forever.

Wake all

One button reloads every napping tab. Badge shows how many are currently asleep.

How it works

Set idle minutes

Default 15. Tabs you forget become candidates for a nap.

Native discard

Chrome freezes the process safely. Click the tab anytime to restore.

Stay in control

Whitelist, pin protection, wake-all. Your rules — nothing sneaky.

Put your tabs to bed.
