TabReaper

About

Too many open tabs slowing down your browser? TabReaper automatically archives tabs you haven't touched in days, frees up memory, and keeps everything recoverable whenever you need it.
No subscriptions. No accounts. Just a cleaner browser.

How it works: TabReaper runs quietly in the background, tracking which tabs you actually use. Any tab that goes untouched past your set threshold gets archived automatically... closed to save memory, but saved so you never lose anything. Restore a single tab or an entire session with one click.
Features:

Auto-archive inactive tabs after 1, 3, 7, 14, or 30 days
Right-click any page and select "Reap This Tab" to archive it instantly
Right-click any page and select "Exclude This Domain" to permanently protect a site from being archived
Tabs reaped on the same day are grouped into a single dated session automatically
Drag and drop tabs between archived sessions to organize them your way
Full session history with one-click restore per tab or entire session
Pinned tabs and your active tab are always protected
Badge count shows how many tabs are waiting in your archive
No account required, no data leaves your browser

Perfect for: Anyone who opens tabs to "read later" and never does, researchers juggling dozens of sources, developers with too many Stack Overflow tabs, or anyone whose browser feels slower than it should.
