FossFLOW Hosting Live In 5 Minutes

Draw infrastructure, network and architecture maps as isometric diagrams in the browser, saved to your own server so the same diagram opens from another browser or device. xCloud configures the pinned FossFLOW image, HTTP Basic authentication with a generated password, persistent diagram storage and HTTPS in minutes.

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

Self-hosting FossFLOW normally means a container, a login wall in front of it, persistent storage for diagrams, a domain and a certificate before a single shape is drawn. This is the same result without assembling any of it by hand.

Step 01
Sign Up
Create your xCloud account and pick FossFLOW from the OneClick catalog. Select a domain and set the HTTP Basic username — it defaults to admin.
Step 02
We Deploy It For You
One click. We bring up the pinned FossFLOW 1.0.4 image, bind the container port to loopback only, require HTTP Basic authentication with a generated 24-character password in front of the editor and its /api, mount fossflow_diagrams, and publish it over HTTPS on your domain.
Step 03
Sign In And Save A Diagram
Open your HTTPS URL and sign in with the username you chose and the generated password from your xCloud credential panel. Create a diagram and save it to Server Storage so it's available from other browsers and devices.

Everything FossFLOW Does, On Your Own Server

FossFLOW runs in full here — the same isometric diagram editor and server-saved diagrams as any hosted diagramming tool, on infrastructure you control.

Isometric Diagram Editor
Draw infrastructure, network and architecture maps as isometric diagrams directly in the browser, built on the Isoflow library.
Diagrams Saved To Your Server
Save to Server Storage and the same diagram opens from another browser or device, instead of staying trapped in one tab.
Whole Site Behind HTTP Basic Sign-In
Every request to the editor and its API is checked against your generated credentials — unauthenticated requests are rejected.
Free And Open Source
MIT licensed, with no per-seat fees — you're paying for the managed server it runs on, not the software.
A Light Footprint
A single container asking for just 1 CPU and 256 MB of RAM, leaving real headroom on any plan.
Diagrams Survive A Restart
Saved diagrams stay in the persistent volume and were still listed and loadable after a container restart in verification.

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.

Gary Moody

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.

Jorge de los Reyes Martínez

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 FossFLOW?

FossFLOW is an open-source Progressive Web App for making isometric diagrams of infrastructure and architecture, built on the Isoflow library. This template deploys version 1.0.4.

Is FossFLOW free?

Yes. FossFLOW is free and open source under the MIT license, with no per-seat fees. xCloud charges for the managed server it runs on, not for FossFLOW itself.

Can I self-host FossFLOW with this template?

Yes — that is exactly what this template deploys. It brings up the pinned FossFLOW image behind HTTP Basic authentication with a generated password, mounts persistent diagram storage, and publishes it over HTTPS on your domain in a few minutes instead of assembled by hand.

How do I sign in?

With HTTP Basic: the username you chose at install and the generated password in the installation credentials. FossFLOW has no in-app user accounts of its own.

Where are my diagrams stored?

On your server, as JSON files in a persistent volume (fossflow_diagrams), as long as you save to Server Storage rather than only locally in the browser.

What runs alongside FossFLOW?

Nothing else. It's one container with its web server and API inside — no database and no additional sidecars.

What does xCloud configure automatically?

The pinned FossFLOW image, HTTP Basic authentication in front of the editor and its API with a generated password, the fossflow_diagrams volume, the container bound to loopback only, and HTTPS on your domain.

What should I back up?

The fossflow_diagrams volume. It holds every saved diagram, and deleting it removes them permanently.

Backups in xCloud

What are the server requirements?

The template manifest asks for 1 CPU core, 256 MB of RAM and 2 GB of disk as a floor — a light single-container app. This page sells the 6 GB tier, which leaves substantial headroom above that floor.

How do I change the login username or password?

Edit HTTP_AUTH_USER / HTTP_AUTH_PASSWORD in the environment editor and Save & Redeploy. Keep ENABLE_SERVER_STORAGE set to true, or the API stops and diagrams stop being stored on the server.

Does xCloud automatically back up or update FossFLOW?

No. The template pins FossFLOW by immutable digest; a catalog re-sync affects new installations only. Read the upstream release notes and take a backup of fossflow_diagrams first, then bump the image tag and digest together to upgrade.

Is xCloud officially partnered with FossFLOW?

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