Cozystack
Cozystack is a free, open-source cloud platform based on Kubernetes that turns bare metal servers into an API-driven infrastructure for spawning Kubernetes clusters, databases, VMs, and other services.
Description
Cozystack is a free, open-source cloud platform built on Kubernetes that transforms bare metal servers into an intelligent, API-driven infrastructure system. It provides a REST API for spawning Kubernetes clusters, databases, virtual machines, load balancers, HTTP caching services, and other resources. Designed as a self-hosted alternative to AWS and a VMware alternative, Cozystack emphasizes standardization, performance, and community collaboration. It uses proven open-source tools, offers easy installation via PXE or ISO, and includes built-in monitoring, alerts, and a web UI for application management. The platform is CNCF-certified Kubernetes and aims to deliver high performance with low overhead, making it suitable for building private clouds or cost-effective development environments.
Features
API-first design with native Kubernetes RESTful API for declarative service provisioning Easy installation via PXE or ISO using talos-bootstrap with immutable OS for consistency Easy integration with billing systems via YAML manifests submitted to Kubernetes API Extensible architecture where each package is a set of YAML files managed by FluxCD High performance and low overhead with efficient tenant model for control plane resource allocation Built-in monitoring and alerts with pre-configured dashboards for each service Web UI for visual application deployment and management CNCF-certified Kubernetes compliance
Benefits
Cost-effective self-hosted cloud alternative to AWS, reducing vendor lock-in Open-source VMware alternative for virtualization workloads AI-ready infrastructure with Kubernetes-native orchestration Standardization and unification using widely known open-source tools Community-driven with contributions to upstream projects Easy to set up and maintain with immutable OS and automated bootstrap Scalable and performant for production workloads
