Harper Hosting Live In 5 Minutes

Deploy Harper hosting and give your team a private grammar and spell-check editor on your own domain. xCloud runs the pinned Harper 2.12.0 web image with a private MariaDB 12.2 database, generates the database credentials, mounts a persistent volume and publishes the editor over HTTPS in minutes — checking runs in the visitor's browser, so writing is never sent to an external grammar service.

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

A Harper stack normally means a web container, a private database, generated credentials, a volume, a domain and a certificate before the first sentence. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick Harper from the OneClick catalog. Choose your domain and target server — there are no extra fields to fill in.
Step 02
We Deploy It For You
One click. We bring up the community-built Harper web image, pinned by immutable digest, with a private MariaDB 12.2 database kept off the public internet, mount the harper_db volume, generate the database credentials, and publish it over HTTPS on your domain.
Step 03
Open The Editor
Open your HTTPS Harper URL, then follow "Open the full editor" or go straight to /editor. Type or paste text and review the suggestions as you write — there is no account to create.

Everything Harper Does, On Your Own Server

Harper runs in full here: a browser-based grammar and spell-check editor on your own domain, backed by a database you own.

Grammar And Spell Checking
Checking runs locally in the browser via WebAssembly, so a privacy-first alternative to cloud grammar checkers never sends your writing to a third-party service.
A Ready Editor At /editor
Type or paste text and see suggestions as you write, with no setup beyond opening the page.
No Accounts To Manage
There is no sign-in system; restrict access with xCloud Basic Authentication or IP management if the editor should not be public.
English Grammar And Spelling
Upstream currently supports English only.
Private MariaDB Included
MariaDB 12.2 is reachable only inside the install's private network, with no published port.
Admin Pages Disabled
The upstream /admin pages are disabled in this image and return 404, keeping the surface area to the editor itself.

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.

What is Harper?

Harper is an open-source, privacy-first English grammar and spell checker. Checking runs in the visitor's browser via WebAssembly rather than on a remote service. This template deploys version 2.12.0.

What makes Harper different from cloud grammar checkers?

Checking runs in the browser rather than on a remote server, so your text stays with you.

How do I sign in?

You don't: there are no accounts. Open /editor on your domain.

What runs alongside Harper?

A private MariaDB database that stores data the site itself collects, such as lint reports. It is not exposed to the internet.

Which languages are supported?

Upstream currently supports English only.

Is the editor public by default?

Yes — there is no sign-in, so if the editor should not be public, restrict access with xCloud Basic Authentication or IP management.

Why does the first load of /editor sometimes show a blank page?

The editor downloads a large script and WebAssembly bundle on first load, which can show a blank page for a few seconds before it renders.

What should I back up?

The harper_db volume (MariaDB data). Keep the generated database credentials private.

Backups in xCloud

What happens if I change the domain?

The ORIGIN environment value must equal the site's public HTTPS address. If you change the domain, update ORIGIN and Save & Redeploy.

Does xCloud automatically back up or update Harper?

No. The template pins Harper 2.12.0 by immutable digest; new installations use the pinned release, existing sites are not automatically upgraded. Back up first, 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, 1024 MB of RAM and 4 GB of disk; measured idle use in QA was about 125 MB. This page sells the 6 GB tier as the entry rung, with real headroom above that baseline.

What survives a restart?

Data on the harper_db volume — a stored row was still present after an xCloud Restart in QA, because it is a persistent named volume.

Is xCloud officially partnered with Harper?

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