Cozystack is an open-source cloud platform that turns bare-metal servers into a Kubernetes-based environment for provisioning and managing infrastructure services. Through a Kubernetes-native REST API and web dashboard, organizations can create Kubernetes clusters, databases, virtual machines, load balancers, HTTP caching services, and other offerings. The platform is designed for teams building public or private clouds, replacing VMware, providing hosting services, or creating self-service development environments.

Cozystack emphasizes standard Kubernetes interfaces, established open-source technologies, and extensible packages built from YAML files, helping users integrate services with billing systems and adapt the platform without relying on a proprietary control plane. It supports installation on servers using PXE or ISO methods and uses an immutable operating system approach. Service instances include preconfigured monitoring dashboards and alerts, with options to organize monitoring by tenant or centrally. A built-in interface lets users explore and deploy applications, while a live browser demo showcases the console without requiring installation or signup. Cozystack also serves platform teams, research institutions, regulated organizations, and telecom or edge deployments.
