A Session Buddy alternative that does more than sessions

Session Buddy saves your windows. Larksail does that automatically, with snapshots that restore tab groups, pinned tabs and window positions exactly. It also keeps tabs under control while you work: collections, suspending idle tabs, merging windows and an archive of everything you close.

Switching from Session Buddy: questions

Does Larksail save sessions automatically?

Yes. Larksail takes snapshots of all your windows as you work and offers to restore your last session after a restart.

Are tab groups restored?

Yes. Snapshots keep tab groups with their names and colors, pinned tabs, the active tab and window positions.

Can I keep using Session Buddy while I try Larksail?

Yes. Importing reads a copy of your data and changes nothing in Session Buddy. Importing into Larksail only ever adds; it never overwrites what’s already there.

Is Larksail free?

Yes, with no limits on collections or saved tabs, and no account.
