COPS Hosting Live In 5 Minutes

Deploy COPS hosting and publish your Calibre library on your own domain. xCloud runs the pinned COPS 4.5.4 image behind a gateway that asks for a generated username and password, mounts persistent volumes for settings and your library, and serves the catalog, downloads and OPDS feed over HTTPS in minutes.

What is COPS?

COPS (Calibre OPDS PHP Server) publishes an existing Calibre ebook library on the web. It offers a browsable catalog with search, covers and downloads, an OPDS feed for e-reader apps, and a REST API.

COPS is a read-only front end: it has no upload page and no way to create a library. This template runs the maintained mikespub-org/seblucas-cops fork.

From Sign-Up to a Live Library In Just 3 Easy Steps

A COPS setup normally means a PHP web container, an authentication layer, volumes, a domain and a certificate before the first book appears. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick COPS from the OneClick catalog. Choose your domain, confirm the timezone and the access username — xCloud generates the password.
Step 02
We Deploy It For You
One click. We bring up the COPS container, kept private, behind a small gateway container that enforces HTTP Basic Authentication, mount the cops_config and cops_books volumes, and publish it over HTTPS on your domain.
Step 03
Copy In Your Library
Save the username and password from the installation credentials, then copy your Calibre library (metadata.db plus the author folders) into the books volume and reload. Until you do, COPS shows a "database not found" check page.

Everything COPS Does, On Your Own Server

COPS runs in full here: a web catalog, an OPDS feed and a REST API over your Calibre library, behind a password you control.

Browse, Search And Download
A web catalog of your Calibre library with search, covers and downloads, reachable from any device with a browser.
OPDS Feed For E-Reader Apps
Point KOReader, Foliate, Moon+ Reader or Marvin at the /feed URL and sign in with the same username and password.
REST API
A REST API is available over the same library, behind the same gateway password.
Read-Only On Your Library
COPS never modifies your Calibre library; it has no upload page and cannot create one.
One Password For Everything
COPS has no sign-in of its own, so a gateway enforces HTTP Basic Authentication on the site, feed, downloads and API; QA confirmed 401 without credentials on each.
Settings And Library Persist
The cops_config and cops_books volumes, and the access credentials, survived an xCloud Restart in QA.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

xCloud gave me what no other hosting platform could: the flexibility of a VPS with the convenience of managed WordPress. As a solo founder running an entire business on one server, that combination is an important unfair advantage.

I use Server Avatar and xCloud and I'll sooner use xCloud than Server Avatar personally.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

How do I sign in?

Use the username and generated password from the installation credentials. Your browser asks for them when you open the site, and the same pair works in OPDS reader apps.

Can I upload books through COPS?

No. COPS reads a Calibre library; copy the library into the books volume instead.

What runs alongside COPS?

A small gateway container that enforces the password. The COPS container itself is private and reachable only through the gateway.

Why does the site show "database not found"?

No library is bundled. Until you copy a Calibre library (metadata.db plus the author folders) into the books volume and make the files readable, COPS shows a "database not found" check page.

Which e-reader apps work with the OPDS feed?

KOReader, Foliate, Moon+ Reader and Marvin are named in the template. Enter the OPDS feed URL and the same username and password; OPDS readers support HTTP Basic Authentication.

How do I change the password?

Rotate ADMIN_PASSWORD in the environment editor, then restart. Keep the password private: it is the only thing keeping the library private.

Edit environment variables

What should I back up?

Your Calibre library from wherever it originates, since COPS never changes it, and the cops_config volume (settings and thumbnail cache).

Backups in xCloud

Does xCloud automatically back up or update COPS?

No. The template pins COPS 4.5.4 by immutable digest; new installations use the pinned release, existing sites are not automatically upgraded. Back up cops_config, read the upstream release notes, then bump the readable tag and digest together on your own schedule. Server-level backups and snapshots are available on every Cloud VPS.

What are the server requirements, and why does this page sell 6 GB?

The template's baseline asks for 1 CPU core, 256 MB of RAM and 5 GB of disk; measured idle use in QA was about 29 MiB. Generating thumbnails of very large covers is the main memory peak. This page sells the 6 GB tier as the entry rung, with real headroom above that baseline.

What survives a restart?

The cops_config and cops_books volumes and the access credentials survived an xCloud Restart in QA, because they are persistent named volumes.

Is xCloud officially partnered with COPS?

No. No official partnership or endorsement between xCloud and the COPS project has been verified. This is a deployment and server-management option for the open-source COPS project.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
