## What it is
Calibre-Web is a self-hosted web application for browsing, reading, and downloading eBooks from an existing Calibre database. It provides a responsive web UI, user management, OPDS feeds, metadata editing, and in-browser reading for multiple eBook formats.

## Use cases
- host a web interface for my calibre ebook library
- read epub books in the browser
- serve ebooks to my kobo or e-reader via opds
- manage ebook metadata and collections online
- share an ebook library with multiple users and permissions
- send ebooks to my kindle or e-reader with one click
- self-host an ebook server with docker

## When to choose
- you already maintain a Calibre library and want web access to it
- you need multi-user access with per-user permissions and OPDS support
- you want a self-hosted alternative to cloud ebook services

## When to avoid
- you don't use Calibre and need to build a library from scratch without the Calibre desktop app
- you need a full replacement for the Calibre desktop application's editing tools
- you only need a simple static file server for ebook files

## Facets
- artifact type: application
- maturity: active
- function: web-framework, search-engine, auth, file-upload, http-server
- domain: self-hosted, web-development, files, developer-tools
