Session Vault — Tab & Window Manager

Local-first tab/window session manager. Saves are additive and versioned — nothing is ever silently overwritten or deleted.

Session Vault saves your open tabs and windows as named sessions, and restores them anytime. Unlike other tab managers, Session Vault never silently overwrites or deletes your saved data — every save is a new, versioned entry. Automatic backups run on a timer you control, keeping a rolling history without ever touching sessions you saved manually. Features: - Save all open windows/tabs as a named session, any time - Automatic timer-based backups, with a configurable retention count - Restore any saved session into a new window, without touching your current tabs - Full JSON export/import for your own backup and portability - 100% local — no account, no cloud, no login, nothing leaves your device unless you export it yourself Built after finding that the most common complaint on competing tab managers is silent data loss — an update or a bug wipes out saved sessions with no warning and no way back. Session Vault is built specifically so that can't happen: nothing is ever overwritten in place, only added.
