Saving a group of tabs and getting it all back in another browser. Faster to watch than to read.

The video only loads when you press play: until then YouTube receives nothing.

The app

Your tabs, in any browser

tabteca saves groups of tabs to your account and restores them whole wherever you sign in: the work laptop, home, or a borrowed browser. It also tracks what you open, so you know what you actually use.

    Restorable sessions

    Save a whole research session and open it again in one click, in whichever browser you are on.

  2. 02

    Your private directory

    Keep the links you come back to, apart from the noise of your bookmarks.

  3. 03

    Usage ranking

    Every open is counted, so you can see which URLs deserve a permanent spot and which do not.

  4. 04

    Shared sessions

    Share a group of tabs with another account, read-only or editable, or with a public link.

Frequently asked questions

Before you ask

All the questions →
Is everything here genuinely free?

Every service listed has a real, usable free plan, not just a 14-day trial. When a service only offers a trial period, we say so explicitly on its page.

How often are the limits reviewed?

Free plans change often. We review the directory regularly — last reviewed: Agosto de 2026 — but the source of truth is always each service’s official pricing page.

Can I use these services in a commercial project?

It depends on the service. Some free plans, such as Vercel’s Hobby tier, forbid commercial use; others place no restrictions. Each page spells out the known limitations.
