Libella.app is a home library catalogue for people with more books than they can remember. Add books by scanning the barcode, searching by title, or scanning a whole shelf or the copyright page of older books. Book details come from national library catalogues across Europe and the US (Library of Congress, Deutsche Nationalbibliothek, BnF, Biblioteca Nacional de España, SBN Italy and more) as well as Open Library and Google Books, so it also finds older and local editions that retail databases miss.
Organise books into your own shelves, switch between cover, bookshelf and table views, edit many books at once, and track who borrowed what, with an optional WhatsApp reminder. Import from other catalogs or CSV, export to CSV or PDF, share your library with a public link.
Runs in the browser on phone and computer, no install needed. Interface in English, German, Spanish, Italian, Czech and Slovak. No ads, no third-party trackers. The first 100 books are free forever; larger libraries cost 2.99 €/month or 29 € once.

If your shelves hold older or European books, Libella.app finds them where other apps return nothing. It works on phone and computer without installing anything, keeps your data in one account across devices, and lets you edit many books at once in a table view. There are no ads and no third-party trackers. The first 100 books are free forever, and larger libraries cost 2.99 €/month or 29 € once.
Most book apps rely on retail databases, so they struggle with older, out-of-print and non-English books. Libella.app looks books up in national library catalogues across Europe and the US (Library of Congress, Deutsche Nationalbibliothek, BnF, SBN Italy, Biblioteca Nacional de España and more), so it finds the exact edition you own, even books printed before the ISBN existed. It runs in the browser on both phone and computer: scan on your phone, organise on a big screen.
People with large home libraries who no longer know what they own: book collectors, avid readers, families sorting out an inherited collection, and anyone with older or non-English books that mainstream apps don’t recognise. Many of our users catalogue hundreds of books in their first week.
Libella.app started with a simple problem: a home full of books and no idea what was on the shelves. Existing apps worked well for new English bestsellers, but not for the older and local editions that fill most European homes. So we built a catalogue that asks the libraries themselves, connecting it to national library catalogues across Europe and the US. It is made by a small independent team in Europe.
