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 your entire digital library into a self-hosted reading sanctuary with BookOrbit, an open-source media platform that organizes ebooks, audiobooks, comic archives, and research PDFs within a personal private cloud. Readers can enjoy multi-format media directly through responsive browser readers that support EPUB, CBZ, and M4B formats without external browser extensions. The platform synchronizes reading bookmarks, highlights, and completion statuses across web interfaces, Kobo ereaders, and KOReader devices. An automated metadata enrichment engine queries fourteen upstream bibliographic indexes, downloading cover artwork, chapter breakdowns, author biographies, and series taxonomies. The staging workspace allows librarians to inspect incoming files, review suggested metadata revisions, and embed updated tags directly into physical storage archives before shelving. Custom reading dashboards track annual book goals, calculate daily streaks, and plot reading habit radar charts. Multi-user configurations support distinct per-user collections, granular content permissions, and single sign-on authentication through OpenID Connect providers. Power users can export private OPDS feeds to external mobile reading applications or push books directly to connected Kindle hardware. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GNU AGPL v3.0 licensed.

BookLore centralizes personal electronic book, audiobook, and comic collections into an organized private media server equipped with automated metadata scrapers and e-reader synchronization. Users can drop EPUB, PDF, CBZ, and MOBI files into a watched BookDrop directory to trigger automated format parsing, background cover retrieval, and staged queue imports. Integrated metadata scrapers query Google Books, Open Library, Goodreads, and Amazon to automatically fill synopsis summaries, author records, publishing dates, and review scores. Dynamic Magic Shelves categorize volumes through custom rule-based filters, author collections, and full-text search indexes across your complete literature catalog. The browser-based reader renders documents with adjustable typography, night modes, audio playback controls, text annotations, and persistent bookmarking. Hardware e-readers and mobile devices connect through native Kobo Store emulation APIs, bidirectional KOReader progress synchronization, and OPDS catalog feeds. Multi-tenant permissions provide each household member with private reading statistics, personalized shelves, email book delivery, and direct send-to-Kindle dispatch. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GNU AGPLv3 licensed.

Manga, comics, ebooks, and light novels get a streaming-service-style home in Kavita - a fast, cross-platform reading server for the DRM-free collection you share with family and friends. It natively serves CBZ, CBR, CB7, ZIP/RAR/7z archives, raw images, EPUB, and PDF, with hand-crafted web readers per format: webtoon scrolling, single and dual-page spreads with advanced caching for the comic reader, and a book reader with adjustable fonts, spacing, margins, color themes, and column modes. Reading progress tracks per user, so everyone resumes exactly where they stopped on any device. Metadata parses from filenames, ComicInfo.xml, and EPUB fields, feeding index-backed search, smart filters, collections, reading lists with CBL import, and Want to Read queues. Role-based user management covers age restrictions, per-library access, and OIDC authentication. An OPDS feed connects third-party clients - Panels on iOS, Librera on Android, KOReader on e-ink devices - and a comprehensive REST API supports custom integrations. EPUB annotation and highlight support, custom theming, and full localization round it out. Built with .NET and Angular, it handles 50,000+ file libraries without strain; optional Kavita+ adds AniList scrobbling, recommendations, and external metadata.
