With over 17,700 GitHub stars and continuous development since 2015, Calibre-Web has become the definitive self-hosted digital library solution for book enthusiasts who want beautiful web access to their Calibre collections. The responsive Bootstrap 3 interface delivers instant browsing, searching, and filtering across titles, authors, tags, series, book formats, and languages, with custom shelves for organizing personal reading collections. In-browser reading supports EPUB, PDF, TXT, CBR, CBT, CBZ, and DJVU formats with a configurable EPUB reader featuring multiple themes and page location tracking, while one-click email delivery sends books directly to Kindle, Kobo, and other E-Readers without leaving the interface. Native Kobo sync lets Kobo device owners synchronize their entire Calibre library wirelessly, maintaining reading progress and bookmarks across devices. Metadata management includes editing capabilities with automatic metadata downloading from Google Books, Amazon, and other configurable sources, plus eBook format conversion through Calibre binaries for on-the-fly EPUB, MOBI, AZW3, and PDF conversion. User management provides fine-grained per-user permissions controlling download access, upload rights, editing capabilities, and content visibility based on categories or Custom Column values. Authentication supports local accounts, LDAP directory integration, Google and GitHub OAuth, proxy authentication, and Magic Link login for easy E-Reader access. The OPDS catalog feed enables any compliant E-Reader app to browse and download from the library. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Serious readers organize, convert, edit, and serve their e-book libraries with Calibre - the definitive open-source e-book manager. This deployment runs the full Calibre desktop application on your server, accessible from any browser, so your library lives in one authoritative place instead of scattered across devices. Its conversion engine is the best in the business, translating between every major format - EPUB, MOBI, AZW3, PDF, DOCX, and dozens more - with fine control over fonts, margins, metadata, and structure detection. Metadata management downloads covers, descriptions, series info, and identifiers from online sources, and every field is editable in bulk. Beyond cataloging, Calibre includes a full e-book editor for EPUB and AZW3 internals, a news engine that fetches newspapers and magazines from the web on schedule and converts them into e-books, book comparison tools, and device syncing that sends the right format to each connected reader. The built-in content server exposes your library over HTTP so phones, tablets, and e-readers can browse and download remotely. A deep plugin ecosystem extends everything - metadata sources, format support, store integrations. For power users, the complete CLI (calibredb, ebook-convert) enables scripted library automation. Your books, your metadata, your server - permanent and DRM-free storage under your control.

Consolidate fragmented collections of digital novels, graphic novels, manga, and audiobooks into Grimmory, an open-source media library server that combines automated file sorting with rich in-browser reading environments. The server indexes diverse media formats including EPUB, MOBI, AZW3, FB2, PDF, CBZ, CBR, CB7, M4B, and MP3 files across isolated storage directories. Readers explore literature through specialized browser viewports that provide customizable typography, CFI highlight annotations, two-page comic spreads with right-to-left manga modes, and chapter-based audiobook playback with sleep timers. Automated BookDrop watch folders ingest incoming files, retrieving book covers, author biographies, and community ratings from Google Books, Open Library, and Amazon APIs. Dynamic Magic Shelves organize catalogs automatically using nested boolean rule trees that filter books by page counts, genres, release dates, or narrator identities without server reload overhead. External e-readers access media catalogs through standard OPDS feeds or native Kobo and KOReader synchronization endpoints that match documents by binary content hashes. Built-in email delivery sends formatted books directly to Kindle devices with a single click, while OpenID Connect authentication enforces granular multi-user library permissions.
