Overview

What is COPS?

COPS — for Calibre OPDS (and HTML) PHP Server — is a lightweight web alternative to Calibre's built-in content server. The premise behind the project is simple: Calibre is a fantastic tool for managing an ebook library, but it becomes cumbersome when it comes to distributing it online. COPS takes over by exposing your existing Calibre folder in two formats: a fully compatible OPDS catalog and a navigable HTML interface accessible from any device — smartphone, tablet, or e-ink reader.

Specifically, COPS reads the metadata.db (SQLite) database generated by Calibre directly, without duplicating or transforming it. It offers built-in search (OpenSearch), management of multiple libraries within a single installation, support for Calibre's custom columns and filtering facets. All formats supported by Calibre are served: EPUB, MOBI, PDF, AZW3, CBR, CBZ…

The OPDS feed is consumed by most reading apps on the market (Moon+ Reader, FBReader, KOReader…) as well as Kobo and Sony PRS e-readers. Technically, COPS is written in PHP and requires only a web server with a few standard extensions. Its footprint is intentionally minimal: little code, no dedicated database, very low CPU and RAM usage.

The typical use case is self-hosting a personal or family library: you sync your Calibre folder to the server (via Syncthing, Nextcloud, a network share…) and COPS makes it accessible online, everywhere, on any OPDS-compatible device. You install and maintain the application on your VPS on French soil.

Host COPS at DINAO

No managed container for COPS: this application is installed on a VPS hosted in France (1 vCPU / 512 Mo / 2 Go (hors bibliothèque ebooks) minimum).

COPS needs a level of access to the machine that the managed container, shared between several customers, does not give. Two VPS hosted in France: DINAO installs and manages it for you, or you administer it yourself.

Technical reason: bind mount of a host path (named volumes only in the managed offer).

Option 2 The simplest

  • Priority support included (2-hour response time, DINAO business days and hours)
  • Stated, capped resources (2 vCPU, 2 GB, 20 GB): beyond that, a larger size is offered

Frequently asked questions

You might be wondering…

About COPS 6 questions

Do I need to install Calibre on the server?

No. COPS only reads the metadata.db database produced by Calibre; the Calibre software does not need to be present on the server side.

How do I sync my library to COPS?

Via any sync method: Syncthing, Nextcloud, rsync, a network share, or a mounted Docker volume. COPS detects changes to the database on the next load.

Will my e-readers be able to connect?

Yes, any app or e-reader supporting OPDS (Moon+ Reader, FBReader, KOReader, Kobo…). You just need to enter the URL of COPS's OPDS feed.

Can access be password-protected?

Yes. COPS supports basic authentication, and DINAO can add protection at the web server level (HTTP auth, reverse proxy) for private access.

How many libraries can be served?

Multiple distinct Calibre libraries can be configured within a single COPS installation.

Is this application tested before it is offered?

This application has not yet passed our automatic deployment test. It can still be installed, but we invite you to contact us before ordering: we will then test it as a priority. The deployment template used was last updated on 3 July 2026. Each new version released by the publisher triggers this test again: the date above therefore follows the version actually offered.
