Calibre-Web

Website: github.com/janeczku/calibre-web

Calibre-Web is a free and open-source web application that puts your existing Calibre ebook library behind a browser interface. It reads the metadata database Calibre already maintains, so authors, series, tags, covers and read state stay in sync, and adds a full web reader, OPDS catalogues and per-user access on top of it.

Key Features

• Browse and read: Grid and list views with an in-browser reader for EPUB, PDF and comic formats
• Library sync: Uses the existing Calibre metadata.db, so shelves and metadata stay consistent with the desktop app
• Metadata editing: Edit titles, authors, tags, series, ratings, covers and descriptions from the web UI
• OPDS and e-reader sync: OPDS catalogues plus Kobo and Kindle sync, so devices pull books automatically
• Multi-user: Per-user accounts with roles, public and private shelves, and per-user download permissions
• Ingest and convert: Upload books through the web UI, email, or the optional calibre-bin converter service
• Formats: EPUB, PDF, MOBI, AZW3, CBZ and CBR among others
