☁️ The KaaS SaaS platform for hosters & resellers

Offer Kubernetes as a Service
on your own infrastructure

Cluster Fabrik is the SaaS platform that lets hosters and resellers provision full-stack Kubernetes clusters on their own hypervisor infrastructure — with built-in multi-tenancy, white-label branding, shared or dedicated ingress IPs, and WHMCS billing.

How it works
One request. Full cluster.
Zero babysitting.

Submit a cluster request and walk away. The async job engine handles every step, retries failures, and gives you a full audit trail.

⚡ Provisioning & Automation
From request to running cluster — automatically

Whether you're running 5 clusters or 500, Cluster Fabrik automates the entire lifecycle so your team focuses on infrastructure strategy, not repetitive VM setup.

⚡

Async Job Engine

Every cluster request runs automatically in the background — VM creation, Kubernetes install, Rancher registration — with full retry logic. No babysitting required.

🔌

Multi-provider Abstraction

Connect Virtualizor or Harvester (on request), with Proxmox coming soon. The platform handles each provider the same way — add a new backend without changing anything else.

📋

Full Audit Trail

Every job step is recorded with timestamps, status, and error details. Know exactly what happened at VM creation, SSH bootstrap, and Rancher registration.

🔒

Encrypted at Rest

Provider credentials and kubeconfigs are AES-encrypted in the database. SSH keys never leave the worker. No plaintext secrets, ever.

🔌

RKE2 & K3s Support

Choose the Kubernetes distribution that fits your workload: RKE2 (Rancher Kubernetes Engine v2, hardened production-grade) or K3s (lightweight Kubernetes, low-resource). Both are CNCF-certified and work with all standard tooling.

Team collaborating on infrastructure dashboards
🏢 Multi-Tenancy & Reseller Tools
Your brand. Your pricing. Full customer isolation.

Create customer organisations, set pricing tiers, and let your clients spin up clusters — all under your own brand, fully isolated, integrated with WHMCS.

🏗️

Multi-tenant by Design

Every reseller gets an isolated organisation in Keycloak. Customers only see their own clusters. No cross-tenant data leakage — ever.

💰

Reseller-Owned Node Plans

Define custom VM plans (CPU, RAM, disk, OS) per organisation. Set your own pricing. Customers only see the plans you've assigned to them.

🔗

WHMCS Integration

A thin PHP module connects WHMCS to the Cluster Fabrik API. Provisioning, suspension, termination — all triggered automatically from your billing system.

🎨

White-label Ready

Your domain, your branding, your terms. Cluster Fabrik is the engine — your customers see your product.

🖥️

Self-Service Portal

Your customers provision and manage their own clusters without involving your team.

🛡️ Security & Networking
Enterprise-grade networking.
Configured automatically.

Every cluster gets public IPs, a firewall and automatic ingress with its own HTTPS hostname. No manual network setup.

🌍

Shared or Dedicated Ingress IPs

Route clusters through a shared HA load balancer by hostname, or give a cluster its own ingress IP from your IP pool. Every node gets a public IPv4.

🛡️

Per-Cluster Firewall

Firewall rules are applied automatically to every cluster. Only the ports and protocols you need are exposed — everything else is blocked by default.

🌐

Automatic Ingress & HA Load Balancing

Ingress is deployed and configured as part of provisioning. Traffic is routed automatically with high-availability load balancing — no nginx config files to maintain.

🔗

HTTPS Hostname per Cluster

Each cluster gets a hostname under your base domain with an automatic Let's Encrypt certificate via cert-manager. Custom customer domains are coming soon.

💾

etcd Snapshots

RKE2 snapshots cluster state every 12 hours on the control-plane node. Workload backups are coming soon.

Why Cluster Fabrik
Built on solid open-source foundations

No black boxes. No proprietary formats. Every layer is inspectable and replaceable, and your clusters run on your own infrastructure.

⚡

Scales with your workload

🛡️

Zero lost jobs

Every provisioning task is reliable and resumable. No duplicates, no silent failures — even if a server restarts mid-operation.

🔐

Enterprise auth, day one

Single sign-on, role-based access, and per-reseller user isolation — fully configured and ready without any custom auth code.

🔧

Works with your entire stack

Your clusters work with every Kubernetes tool you already use — Helm, kubectl, Lens, ArgoCD. No proprietary APIs, no lock-in.

Frequently asked questions

Cluster Fabrik supports Virtualizor (full feature set) and Harvester (on request) for bare-metal Kubernetes deployments, with Proxmox support coming soon. Cloud provider support for AWS, Azure, and GCP is in active development. The platform abstracts the provider layer so the same provisioning workflow applies regardless of the underlying hypervisor.
Cluster Fabrik enforces a three-level role hierarchy: Admin then Reseller then Customer. Each level only sees and manages resources within its own scope. Resellers can have multiple customers, customers can have multiple clusters, and audit trails are scoped per tenant. Authentication is handled by Keycloak with OIDC/PKCE.
Yes. Cluster Fabrik ships with a WHMCS integration for hosting providers and exposes a documented API for custom billing systems. Per-cluster usage is tracked and can be exported on a monthly cycle.
Yes. Cluster Fabrik orchestrates RKE2 and K3s lifecycle operations including version upgrades, control plane patches, and node draining. Upgrades are scheduled per-cluster and tracked in the async job engine with full audit history.
Yes. The reseller and customer portals support white-label branding: your logo, colors, and domain on the customer-facing UI. We operate the underlying platform; your customers only see your brand.
