Features

Automatically closes inactive tabs after 3 days

Lightweight and privacy-focused

No tracking, no ads

Keeps your browser organized without manual cleanup

How it works

The extension silently checks when each tab was last active. If a tab stays inactive for more than 3 days, it is closed automatically. Tabs you are currently using are never affected.
