## What it is
COPS is a lightweight PHP web application that serves a Calibre ebook library over OPDS feeds and a simple HTML catalog. It reads the Calibre metadata database directly, requiring no heavy dependencies, and supports search and ebook formats like epub, mobi, and pdf.

## Use cases
- serve my calibre library over opds to my e-reader
- host a lightweight ebook server on a small home server
- browse and download ebooks from my kobo or eink device
- search my calibre collection from a phone without running calibre itself
- replace calibre content server with something low-resource
- sync my calibre library to a nas and access it via web

## When to choose
- you have an existing Calibre library and want a low-resource web/OPDS server
- you run a small server or NAS (e.g. Raspberry Pi, Dockstar) with PHP
- you need OPDS feeds with search for e-readers like Kobo

## When to avoid
- you need active feature development or modern framework support
- you want a full ebook management/editing tool rather than a server
- your stack is not PHP-based

## Facets
- artifact type: application
- maturity: maintenance
- function: http-server, search-engine, image-processing
- domain: self-hosted, files, web-development
- platform: php, self-hosted
- tags: opds, calibre, ebook-server, epub, eink, web-server, linux
