What you can build with COPS
COPS (Calibre OPDS PHP Server) is a fast, read-only alternative to the built-in Calibre content server. It exposes an existing Calibre library — the standard metadata.db file — through a simple HTML interface for browsers and an OPDS feed for ebook readers like Moon+ Reader, KyBook, Aldiko, and Marvin. Because it runs on plain PHP with no database of its own, it stays responsive on modest hardware and starts in seconds.
Self-hosting COPS on a VPS gives mobile ebook readers a fast catalog endpoint without keeping a Calibre desktop instance running, and pairs naturally with Calibre-Web for users who want a read-only public catalog separate from their full management UI.
Key features of COPS
Native OPDS feed
Built-in OPDS 1.1 catalog so mobile reading apps can browse, search, and download from your Calibre library out of the box.
Reads Calibre metadata.db
Points directly at the same SQLite database Calibre uses — no import, no duplicate library, no sync step.
Lightweight footprint
Pure PHP with no external database, so it stays fast on small VPS plans and handles libraries with thousands of titles.
In-browser reader
Reads EPUB files directly in the browser via Monocle, so users can sample books without downloading first.
Custom themes and configuration
Adjustable per-instance through local.php — pick a theme, set page size, restrict access, or expose multiple databases at once.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Kodee and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
