OneTab is a simple, free tab converter that collapses open tabs into a list. TabVault Pro is a full tab management system with workspaces, free cloud sync via Google Drive, and a two-way mobile app. Choose OneTab if you just want to collapse tabs to a list. Choose TabVault Pro if you need to organize, sync, and access your tabs across devices.

OneTab has no sync feature at all. Your saved tabs live in the browser where you created them. If you use Chrome at home and at work, those are two separate OneTab lists with no connection.
TabVault Pro syncs through your own Google Drive account, free for all tiers. Save tabs on your work laptop, access them from your home desktop or phone. Your data stays in your Google Drive storage, not on third-party servers.
OneTab has no mobile app. There is no way to view or manage your saved tabs from a phone or tablet.
TabVault Pro has native apps for both Android and iOS with full two-way sync. You can save tabs from your phone, organize them into workspaces, and find them waiting on your desktop when you get back. It works both ways.
OneTab keeps things simple. You click the button, your tabs collapse into a flat list. You can drag items to reorder, lock groups, and star individual tabs. That is the full extent of its organization system.
TabVault Pro gives you a layered structure: workspaces for different projects or contexts, collections within each workspace, plus auto-categorization rules, tags, and color coding. If you manage tabs for multiple projects, clients, or research topics, this structure makes a real difference.
Both extensions are local-first, meaning your tab data stays on your device by default. Neither sends your browsing data to external servers for processing.
TabVault Pro's cloud sync uses your own Google Drive account. Your data lives in your storage, under your control. You can disconnect sync at any time and everything stays local. Tab data syncs through your own Google Drive rather than third-party servers.
OneTab is completely free with no paid tiers, no limits, and no upsells. That is genuinely its biggest strength. If you want a zero-cost solution and the feature set works for you, OneTab is hard to beat on value.
TabVault Pro has a generous free tier (3 workspaces, 5 collections, 50 tabs, cloud sync, mobile app). Power users can upgrade to Pro (€29.99) or Pro+ (€59.99) as one-time payments for more capacity and features like screenshot previews. No subscriptions, no recurring charges.
€29.99 once vs €0 (OneTab) — but TabVault Pro's free tier includes cloud sync, mobile, and workspaces that OneTab does not offer at any price.
Both are good tools. The right choice depends on what you actually need from a tab manager.

TabVault Pro is a privacy-first tab manager with free Google Drive cloud sync and a two-way mobile app for Android and iOS. It is one of the few Chrome tab organizers that lets you save tabs on your laptop and access them on your phone without a subscription or external account.
No. OneTab stores everything locally in your browser. If you clear your browser data, reinstall Chrome, or switch to a new device, your saved tabs are gone. There is no built-in sync or backup feature.
