BiblioGenius

BiblioGenius keeps your books in order, lets you share them, and never forgets who borrowed what.

Scan a barcode and the book appears with its cover, blurb and details, pulled from open catalogues: the French National Library (BnF), Inventaire and OpenLibrary. Google Books stays optional, off by default, and needs your own API key. Shelve the book, track your reading, record who you lent it to.

Peer-to-peer lending sits at the centre of the app rather than being bolted on. Scan a friend's QR code and their library shows up on your phone. Ask to borrow a title, they accept, and the app follows the rest: who has the book, since when, and when it is due back. Exchanges run peer-to-peer and are end-to-end encrypted.

Everything works offline. No mandatory account, no ads, no tracker. The account is optional: when you create one it only ever holds an end-to-end encrypted copy of your library, unreadable by the server, for backup, recovery and multi-device sync.

Also included: import from Goodreads, Babelio, Gleeph and inventaire.io, full library export, series tracking, wishlist, ready-made reading lists and reading statistics.

BiblioGenius is free, published under the AGPL-3.0 licence, and developed in the open on Codeberg.
