Calibre-Web is a web application that puts a clean browser interface on top of an existing Calibre eBook library. It reads a valid Calibre database so that users can browse, read and download books from any device with a web browser. It is released under the GPL v3 license.

Administrators get a graphical setup, an admin interface and detailed user management with per-user permissions, and logins can use LDAP, Google or GitHub OAuth, or proxy authentication. Readers can search and filter, create shelves, read books in the browser in several formats, and use an OPDS feed with eBook reader apps. Books can be sent to e-readers in one click, and Kobo devices can be synced with the library.

Further features include metadata editing and downloading from various sources, eBook conversion through Calibre binaries, uploading new books (audio formats included), Calibre custom column support and hiding content per user. Installation is recommended through pip inside a virtual environment, and Docker images are also available.

Audiobookshelf is a self-hosted server for audiobooks and podcasts. You point it at folders of audio files on your own hardware, and it serves them to a web player and companion mobile apps, so your collection stays on machines you control.

The server streams all audio formats on the fly, keeps listening progress per user and syncs it across devices, and supports multiple users with custom permissions. It can search for podcasts and auto-download new episodes, fetch metadata and cover art from several sources, edit chapters, merge files into a single m4b and embed metadata into audio files. Basic ebook support covers EPUB, PDF, CBR and CBZ, and ebooks can be sent to a device such as a Kindle.

Audiobookshelf is released under the GPL-3.0 licence and is fully open source, including the Android app and the iOS app, which are both in beta. A Progressive Web App, Chromecast support, automated daily backups and open RSS feeds are also available. Folder structure and naming affect how the library is detected, so the documentation on organizing media is worth reading first.

Kavita is a cross-platform reading server written in C#. You run it on your own machine, point it at your collection of comics, manga, webtoons and books, and read through responsive web readers on a phone, tablet or desktop, with the option to share the collection with friends and family.

It handles formats such as CBR, CBZ, ZIP, RAR, 7-Zip and raw images for comics, and EPUB and PDF for books. The library offers rich metadata with filters and smart filters, collections, reading lists with CBL import, and a want-to-read list. Readers support webtoon and continuous modes and virtual pages for EPUB, themes can be customized, and EPUB annotations and highlights are available. Role-based user management covers age restrictions and OIDC.

Extra metadata, reviews, ratings, recommendations and scrobbling are available via the optional Kavita+ service. Kavita is licensed under GPL-3.0, offers a public demo and a wiki for installation on various platforms, supports OPDS feeds, and the maintainers describe it as beta software until a 1.0.0 release.

Komga is a media server for digital comics, manga, bandes dessinees, magazines and eBooks. You point it at your files, and it presents libraries, series and books through a responsive web interface that works on desktops, tablets and phones.

It supports collections and read lists for organizing a library, metadata editing and automatic import of embedded metadata. A built-in web reader offers several reading modes. Several users can be managed, with per-library access control, age restrictions and label restrictions. For other apps and devices it offers a REST API, OPDS v1 and v2 feeds, Kobo Sync for Kobo eReaders and KOReader Sync. Further tools include downloading books, series or read lists, duplicate file and duplicate page detection, and importing ComicRack read lists.

Komga is written in Kotlin on Spring Boot, released under the MIT licence and typically run with Docker. It is self-hosted software, with installation instructions and documentation on the project website and a Discord server for community help.

Open Library is an open, editable library catalog run by the Internet Archive, with the goal of having a web page for every book ever published. This repository holds the code behind the openlibrary.org website, which is operated as a public service rather than something most people install themselves.

On the site, visitors can search and browse by subject, view trending titles, explore virtual shelves in Library Explorer, search inside the text of books, and borrow books online through Controlled Digital Lending. Readers can keep a reading log, create lists, set yearly reading goals and browse collections such as a K-12 student library. Anyone can contribute by adding books, correcting records or volunteering as an Open Librarian, and a Developer Center covers the API.

The software is written in Python and released under the AGPL-3.0 licence, and the interface is available in many languages. The project is nonprofit and accepts donations.

Calibre-Web Automated, formerly Calibre-Web Automator, builds on Calibre-Web to give you a self-hosted digital library that handles much of the routine work for you. It is aimed at readers who keep an eBook collection on a home server and want less manual upkeep.

The maintainer explains the motivation: containerized Calibre depends on a KasmVNC interface that is hard to use on mobile and heavy for small servers, while Calibre-Web is light and modern but lacks some core Calibre features, which leads many people to run both side by side. Calibre-Web Automated aims to combine the lightweight Calibre-Web interface with Calibre's feature set and add automations. Repository topics reference automatic import, format conversion, Kindle, Kobo and KEPUB support, and the README documents KOReader syncing and OAuth authentication.

The project is licensed under GPL-3.0 and is installed with Docker Compose, which the README recommends, including a path for users migrating from stock Calibre-Web. The maintainer states it will always be free and open source and accepts voluntary support.

Grimmory is a digital library you host yourself, built for avid readers. It organizes ebooks, comics and audiobooks on your own server, with a web interface for browsing, searching and reading, so your collection is not locked inside a single vendor's store or app.

Features include smart shelves that filter by rules and tags and support full-text search, and metadata lookup that pulls covers, descriptions, reviews and ratings from Google Books, Open Library and Amazon, all of which can be edited. A built-in reader displays PDF, EPUB and comic files inside the browser, with support for annotations, highlights and progress tracking. Devices can sync through Kobo, any OPDS-compatible app or KOReader, and multiple users can have separate shelves. Topics list many formats and OIDC sign-in.

Grimmory is built with Java and Angular, licensed under AGPL-3.0, and documented with a quick start guide and Discord community. It suits book collectors and households that want a private, shared reading library.
