A namespace per customer is quick to set up, but every customer still talks to one API server and often lands on the same nodes. vCluster moves each customer into a tenant cluster with its own virtualized control plane, on Private Nodes in production.
Namespace per customer Kubernetes shares control-plane and often worker-node components between customers.
Namespaces share the Kubernetes API server and cluster-level components between customers.
A separate management stack for every customer increases infrastructure and operational work.
Building custom tenant isolation requires ongoing work across access, capacity, networking, observability, and lifecycle operations.
vCluster Platform gives each customer a separate tenant cluster with its own virtualized control plane. Private Nodes provide dedicated production worker capacity while operators retain central policy and fleet control.
Move beyond namespace per customer Kubernetes with separate tenant control planes, Private Nodes, and centralized operations.
Private Nodes dedicate worker capacity, networking, and storage to one production customer cluster at a time.
Each customer receives a separate virtualized API server and RBAC boundary on the control plane cluster.
Tenant clusters use a certified Kubernetes distribution and standard APIs for existing tools, CRDs, and operators.
vNode uses Linux user namespaces and seccomp filters to strengthen the runtime boundary for workloads that need additional isolation.
vCluster Platform supports air-gapped deployments and FIPS features on supported plans for controlled environments.
This isn’t a side project. Behind every vCluster deployment is 5+ years of deep K8s engineering, security hardening, and battle-tested infrastructure work at massive scale.

Namespace per customer Kubernetes shares one API server and node-level components across customers. That model fits trusted internal teams, but external or untrusted production tenants need a stronger control-plane and worker-node boundary.
vCluster gives each customer a separate virtualized API server and RBAC boundary. Private Nodes are the production default and dedicate worker capacity, networking, and storage to one tenant cluster at a time.
Yes. Customers can receive cluster-admin inside their own tenant cluster, including control of CRDs and RBAC, without access to the provider's control plane cluster or another tenant environment.
vCluster Platform supports air-gapped deployments and FIPS features on supported plans. Compliance still depends on the customer's complete deployment, configuration, and operating controls.
Customer clusters come up in minutes, not hours, much like creating a namespace. Private Node readiness depends on whether worker capacity is available or must be provisioned.
Templates, access, quotas and observability for every customer cluster live in one UI, CLI and API. vCluster Labs software powers 100K+ GPUs across 50+ GPU clouds and Fortune 500s, and Lintasarta runs 170+ tenant clusters in production.
