Wisp – Tab Suspender to Save RAM

About

Wisp frees up memory by putting your inactive tabs to sleep — and unlike the old suspenders, it never loses them.

Most tab suspenders replace your tab's real address with their own page. Uninstall the extension, restart the browser, or hit a bug, and your tabs are gone. Wisp doesn't do that. It uses Chrome's built-in native tab discarding, so a sleeping tab keeps its real URL, title and favicon — your tabs survive restarts, uninstalls, and session managers. Featherlight, by design.

WHY WISP
• Never loses your tabs — native discard keeps the real URL; nothing to "recover"
• Actually frees RAM — real native discarding, not a fake placeholder page
• 100% local — no account, no login, no tracking, no network calls. Ever.
• Works on Chrome, Brave, Edge, Vivaldi and Opera (Manifest V3)
• Speaks your language — 14 languages, auto-selected

NEVER SLEEPS THE WRONG TAB
Wisp checks the page at the last moment before sleeping it, so it won't discard a tab you're using. It never sleeps tabs that are:
• playing audio or video
• holding unsaved form input (it won't eat your half-written comment)
• pinned
• active / on screen
Plus your own exceptions: keep any tab or any whole domain awake with one click.

KEEPS YOUR PLACE
When a slept tab wakes up, Wisp restores your scroll position and form input — so you pick up exactly where you left off (passwords are never captured).

SIMPLE, OR POWERFUL
One-click popup for the essentials; an Advanced page for the timer (in minutes), protection rules and your never-sleep domain list. Right-click menu and keyboard shortcuts included.
