Chrome eats RAM when you keep 30+ tabs open. Sloth doesn't close them — it hibernates them. Tabs stay in your bar, use 0 RAM, wake instantly when you click.

You need tabs open for context. Your RAM doesn't. Sloth gives you both.
Chrome's tab discard unloads a tab from memory but keeps it in your tab bar. 20 tabs = ~900MB saved instantly. Check chrome://discards to verify.
Closing tabs loses context. Hibernating keeps them. Shopping carts, docs, research - all still there, just sleeping. Click to wake, no reload lost.
No cloud, no API, no tracking. All logic runs locally in your browser. No data ever leaves your machine. Works offline, even on a flight.
Select all, or select only the trash. Hibernate 23 tabs in one click. No more Cmd+W, Cmd+W, Cmd+W guilt.
Export your open tabs as a clean Markdown file before hibernating. Perfect for weekly cleanup or moving to another device.
No login, no analytics panel, no “productivity score”. Just a 400px popup that does one job well and disappears.
Uses Chrome's native discard API - the same thing Chrome uses internally.
Click the sloth icon. It instantly lists all tabs across all windows. No loading, no AI download.
By default, all non-active tabs are selected. Uncheck the ones you want to keep awake. Active tab can't be hibernated.
One click. Tabs turn faded, show as sleeping, RAM freed. Click any sleeping tab in your tab bar to wake it instantly.
GitHub issues, Stack Overflow, localhost, docs - keep them all. Hibernate when you switch branches. 15 tabs of docs = ~675MB back.
20 papers, Notion, Drive, Medium articles. Don't close, hibernate. Export as Markdown for your weekly review.
Amazon, Flipkart, Myntra carts you’ll “buy later”. Hibernate instead of buying now. Sloth rewards laziness.
That Gmail with 11,313 unread? Hibernate it. It will still show the unread count, but use 0 RAM until you need it.
