Building Massively Multi-Tenant Platforms. Together.

An open source horizontally scalable control plane for Kubernetes-like APIs.

Get Started Learn More

A Framework for Platforms

kcp allows building platforms and SaaS-like services with technology already known to platform engineers: Kubernetes and its API capabilities.

Multi-Tenancy at Scale

Workspaces allow teams to work without interference from others when consuming platform services. Meanwhile, services are implemented as global operators.

Dedicated to Community

kcp is a CNCF Sandbox project and is proud to be part of the community. We value respectful collaboration with contributors and upstream projects above all.

Our Project Goals

Multi-Tenancy for Peace of Mind.

kcp implements fully-isolated workspaces, each acting as its own Kubernetes-like cluster, with its own URL endpoint, its own set of APIs (e.g. different CRDs), its own RBAC, but as cheap and quick as a namespace.

APIs as a Service.

kcp extends Kubernetes’ CRD extension model to an API export mechanism optimized for SaaS service providers offering APIs to thousands or many tens of thousands of user workspaces – Securely and efficiently.

Building Block, Not Walled Garden.

kcp does not replace Kubernetes, but complements it as a backend to host Kubernetes-like APIs as SaaS. It’s a flexible framework for building platforms.

Work at Global Scale.

kcp schedules workspaces to kcp instances called shards, similarly to pods get scheduled to nodes. Our ambitions are to eventually reach 1 million workspaces and 10,000 shards.

Beyond Compute.

kcp intentionally only knows generic APIs, no pods or related resources. Our goal is to build a control plane for form factors beyond container orchestration.

Based on Kubernetes. Not a Fork.

kcp takes full advantage of Kubernetes API conventions, the glue that binds the Cloud Native Native technology ecosystem together and imbues Kubernetes’ popular end-user experience. We live and breath Kubernetes and the community. No compromises.

We ❤️ Collaboration

We develop kcp completely in the open. Everybody is welcome to help making the vision of kcp reality.

Meet us in person in the #kcp-dev channel in Kubernetes Slack. Find our code on GitHub.
