Yes. Saving, restoring, suspending, groups, folders, tags, search and sharing are free with unlimited local storage. Pro adds cloud sync and backup; Team adds shared workspaces.
Suspending unloads an idle tab from memory while keeping it in your window. Click it to reload instantly. You can also auto-suspend tabs after a set idle time.
Your saved sessions live on your device, so uninstalling the extension removes them with it. Pro keeps a copy in the cloud, which is what carries your sessions to a new browser or a new machine.
Yes. Sessions are stored on your device by default, and signing in is optional. It is only needed for cloud sync, Teams and the Pro AI features. A share link is unlisted and expires on its own, and you can revoke it at any moment. We never sell your data and never run trackers.
The AI can name a saved session from what is in it, group loose tabs by what they are about, and find a session by meaning rather than exact wording. It is powered by a third-party API, which receives the titles and web addresses of your saved tabs. Page contents, cookies and form data are never sent. It is a Pro feature, so nothing leaves your device on the free plan.
Each AI action costs a credit or two, and Pro includes 300 a month, enough for everyday use. A Team pools 300 per seat across everyone. You are only charged when the AI actually answers: a repeated request served from cache, or one our own code handled, costs nothing. If you run out you can buy more, and they never expire.
Chrome, Edge, Brave, Opera and Vivaldi via the Chrome build, plus Firefox.
Yes. NestarioTabs imports your existing sessions from OneTab and Session Buddy in a couple of clicks, nothing gets left behind.
NestarioTabs is local-first. Your sessions live on your device unless you choose to sync them.
Your tabs are saved right on your machine. Nothing leaves it unless you switch on sync.
No ads, no tracking, no selling your data. We make money from Pro, not from you.
A share link is unlisted, dies on its own after 7 days on Free and up to a year on Pro, and you can revoke it before then.
Saving, restoring, suspending and searching all work signed out. No account, no email, no strings.
