TabGroup Vault

The short version: TabGroup Vault is a solid, no-subscription option if tab-group loss has actually cost you real time before — the $39 one-time price is steep for casual use but fair for a tool you'll use daily.

Compared to Session Buddy, OneTab, or Tab Manager Plus, most of which either charge a recurring subscription or focus on tab reduction rather than group preservation, TabGroup Vault's one-time lifetime payment is the standout differentiator — no ongoing cost once you've bought Pro. The 4.6/5 rating and 800+ active users suggest it does what it claims reliably, and Google Drive backup plus multi-profile support cover the two most common real-world snags (switching computers, separating work/personal contexts). The free tier's 10-snapshot cap is fine for testing but too small for anyone with more than a couple of ongoing projects, and snapshots are manual — there's no automatic background saving, so forgetting to snapshot before a crash still means losing that session. Best fit: developers, researchers, and remote workers who routinely run 30+ tabs across multiple projects and have been burned by losing them. Weaker fit: casual users who rarely have more than a handful of tabs open — $39 isn't worth it for occasional use.
