WHMCS Kubernetes & cloud — the Cozystack integration for hosters

Open-source Cozystack (a CNCF project we create and maintain) → Ænix Platform, the supported commercial distribution → Aenix builds, operates and migrates it.

The Aenix 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 Aenix product 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 Aenix 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, Kafka, ClickHouse, RabbitMQ, NATS), VMs, message brokers, 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); the WHMCS module itself is a proprietary Aenix product.
Time to offer Days, not quarters — 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, Kafka, ClickHouse, RabbitMQ, NATS — 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, metered like any other service.

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, in days 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 a proprietary Ænix product, delivered and supported by the team behind Cozystack.

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.

See the Ænix Public Cloud Platform economics and the anonymized sovereign public cloud case study.

Ænix is the team behind Cozystack — a CNCF project (Sandbox today; Incubating expected late summer 2026), Apache 2.0. Ænix commercializes it as Ænix Platform, as three platforms on one engine — Public Cloud, Private Cloud and AI — that combine rather than exclude each other.

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, Kafka, ClickHouse, RabbitMQ, NATS), virtual machines (KubeVirt-based, Linux and Windows), message brokers and queues, 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?

The underlying platform, Cozystack, is open source (CNCF, Apache 2.0). The WHMCS integration module is a proprietary Aenix product, delivered and supported by Aenix.

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.
