Citadel

Fast desktop app to manage an ebook library, backwards compatible with Calibre.

Desktopfree

Citadel is a desktop ebook library manager that is backwards compatible with Calibre, aiming to be faster and better-looking while keeping libraries fully readable by Calibre itself. It targets existing Calibre users who want quicker browsing and editing but don't need Citadel to also serve as their reader, since it opens books in the user's default apps.
