WHMCS Kubernetes and cloud: the Ænix module for hosters

Book a call Open the live demo →

Open-source Cozystack (CNCF project, created by Ænix) → Ænix Public Cloud, Private Cloud and AI Platform → Ænix builds, operates and migrates them.

The Ænix WHMCS integration plugs Cozystack straight into the billing panel you already run: your customers order modern cloud services from WHMCS, you bill them through WHMCS, and Cozystack provisions and meters them — no separate control plane, no rip-and-replace. It is a proprietary Ænix module, not part of open-source Cozystack, and it is included in every tier of the Ænix Public Cloud Platform subscription (from $1,250 per 10 nodes per month). It is built for hosting providers, ISPs, MSPs and regional clouds that want to add Kubernetes, databases, VMs and GPU to their offering without building a cloud platform from scratch.

Quick facts

What it is A proprietary Ænix module that connects Cozystack service provisioning and metering to WHMCS billing.
Who it's for Hosting providers, ISPs, MSPs and regional clouds already running WHMCS (or planning to).
Services exposed Managed Kubernetes, databases (PostgreSQL, MariaDB, Valkey, ClickHouse), VMs, message brokers (Kafka, RabbitMQ, NATS), S3-compatible object storage, GPU workloads.
Billing Provisioning, metering and invoicing flow through your existing WHMCS billing.
Foundation Open-source Cozystack (CNCF project, Apache 2.0) underneath; the WHMCS module itself is proprietary Ænix software.
Price Included in every Ænix Public Cloud Platform tier: Basic $1,250, Standard $3,000, Plus $5,500 per 10 nodes per month, Enterprise custom.
Time to offer Live in weeks once the hardware is ready, through the productized installer — new services on the panel your team already knows.

Sell Kubernetes clusters, managed databases, virtual machines, message brokers, object storage and GPU straight from WHMCS. Your customers order, you bill, Cozystack provisions — no separate control plane, no rip-and-replace.

Pairs with: Ænix Public Cloud Platform — the full platform for organisations selling cloud (branded portal, service catalog, support), of which this integration is one component. New to the engine underneath? Start with Cozystack.

What your customers can self-serve from WHMCS

The integration exposes the Cozystack service catalog as WHMCS products your customers order themselves:

Managed Kubernetes Multi-tenant Kubernetes clusters with isolation, quotas and RBAC per customer — sold and billed as a WHMCS product.

Managed databases PostgreSQL, MariaDB, Valkey, ClickHouse — provisioned on demand, metered and invoiced.

Virtual machines KubeVirt-based VMs, Linux and Windows, with custom image/template upload.

Message brokers & queues Kafka and RabbitMQ/NATS messaging as ready-to-order services.

S3-compatible object storage SeaweedFS-backed buckets your customers create and pay for by usage.

GPU workloads GPU-backed workloads for AI/ML and rendering. GPU usage is measured per tenant, and charging happens in WHMCS.

Provisioning, metering and invoicing all flow through your existing WHMCS billing — no second billing system to reconcile.

Why it matters for your hosting business

New services, same billing — Kubernetes, databases, VMs and GPU on the WHMCS workflow you already operate, live in weeks rather than quarters.
More margin per customer — managed services priced per service, instead of competing on shared-hosting price per vCPU.
No platform to build — Cozystack is the cloud platform; the catalog arrives without a multi-year platform-engineering project.

The module itself is proprietary Ænix software, delivered and supported by Ænix and included in every Public Cloud Platform tier.

Beyond WHMCS

Not on WHMCS, or running something else? We also help hosters and clouds:

Migrate workloads off other hosting panels, OpenStack, VMware and legacy stacks — see migration and VMware alternative.
Integrate Cozystack and billing with other control panels.
Package and add the specific apps and services your customers ask for.

Model the business in the hosting-provider unit economics calculator, see the Ænix Public Cloud Platform, read the anonymized sovereign public cloud case study, and watch the recorded webinar Add Kubernetes, databases and GPU to your price list, which uses WHMCS as a worked example.

Ænix created Cozystack, a CNCF project (Sandbox today; Incubating application in due diligence) under Apache 2.0, and maintains it with maintainers from other companies. Ænix sells three platforms on it — Public Cloud, Private Cloud and AI.

Frequently asked questions

What does the WHMCS integration actually add?

It lets your WHMCS customers self-serve modern cloud services — managed Kubernetes, databases, VMs, message brokers, object storage and GPU — while provisioning, metering and invoicing run through your existing WHMCS billing. Cozystack is the platform underneath; WHMCS stays your commercial front.

Which services can I sell through it?

Managed Kubernetes clusters, managed databases (PostgreSQL, MariaDB, Valkey, ClickHouse), virtual machines (KubeVirt-based, Linux and Windows), message brokers and queues (Kafka, RabbitMQ, NATS), S3-compatible object storage, and GPU workloads for AI/ML and rendering.

Do I have to replace my current setup?

No. The integration adds services on top of the WHMCS panel you already run — no separate control plane and no rip-and-replace. Cozystack runs on your own or leased bare metal.

Is the plugin open source?

No. The underlying platform, Cozystack, is open source (CNCF, Apache 2.0). The WHMCS integration module is proprietary Ænix software, delivered and supported by Ænix.

How is it priced?

It is included in every tier of the Ænix Public Cloud Platform subscription, which is priced per 10 physical nodes per month: Basic $1,250, Standard $3,000, Plus $5,500 on annual billing, and a custom Enterprise tier. There is no separate charge for the module.

We use a different control panel — can you still help?

Yes. We integrate Cozystack and billing with other hosting panels too, migrate workloads off other panels, OpenStack, VMware and legacy stacks, and package the specific apps and services your customers ask for.
