What is it?

Calibre-Web gives you a browser-based front end for a Calibre ebook library. It reads an existing Calibre metadata database and serves its books with a responsive interface for searching, filtering, reading in the browser, and downloading files.

The app supports multi-user access with per-user permissions, an admin interface, and public registration if enabled. It can serve an OPDS feed for ebook reader apps, send books to e-readers, sync Kobo devices, and allow uploads. Login can use LDAP, Google or GitHub OAuth, or proxy authentication.

It can also edit metadata, fetch metadata from external sources, and convert books through Calibre binaries when they are installed. Installation is available via pip or Docker images.
