In validation · demand check before any code

Save your tab sessions without handing them to someone else's cloud

TabVault is a planned tab session / workspace manager for Edge and Chrome. It is not built yet. This page exists to answer one question first: do enough people want a local-first session manager — no account, data stored only in the browser — to justify building it? If yes, it gets built. If not, it doesn't.

Why this shape

Popular session tools prove the need: Session Buddy lists about 1,000,000 Chrome users with a 4.7-star average across roughly 25,000 ratings (Chrome Web Store figures, checked 2026-10-09).
Subscription workspace tools such as Workona (Pro from $7/month) require an account and store your workspaces in their cloud — a recurring reason people give for looking for alternatives.
Switching is the blocker: users of existing tools have asked for a way to import their saved Session Buddy sessions before they can migrate at all. Import comes first here, not as an afterthought.

Planned capabilities (none of this exists yet)

Save and restore tab sessions and windows, stored locally in the browser — no account, no server
One-click import of existing Session Buddy and Tab Session Manager session data
Search and organise saved sessions
Pro (planned): automatic save rules, session version history, bulk cleanup

This page promises nothing that is not written above. Features, if the product is built, will follow what registrants actually ask for.

Who this is for

People who routinely keep dozens of tabs or several research windows open
People who want session backup without an account or cloud copy
If a free tool already covers your needs, you do not need this — the free version of this idea, if built, would keep saving/restoring/import free anyway

Indicative price (not a live price — nothing is for sale, no payment is taken)

$19 one-time for Pro

Registering is just sending one email — no payment, no pre-order, no commitment to buy. Please include what you use today for tab sessions: that answer matters more than the signup count, because it shows the switching cost this would need to beat.

This tool is not built yet. Development will only begin if 20 people join this waitlist by November 8, 2026; if that goal isn't met, the project will be dropped and every registrant notified by email. The price and threshold are test parameters for this validation, not market conclusions.

Questions

Can I use it now?
No. Nothing has been built; this page is the whole thing.

Does registering mean I have to buy it?
No. It only means "notify me if it launches". Decide when there is a real product to look at.

Why validate before building?
Browser session tools are a crowded category with strong free options. Building first and hoping would waste your attention and my time; a signup count plus real answers about current tools is a cheaper, more honest test.

Why Edge first?
The extension would be built on a Chromium base that works in both Edge and Chrome; the store listing would start on Edge, with Chrome following the same codebase.
