Kusion is an open-source, AI-enhanced Infrastructure-as-Code (IaC) platform built for managing complex cloud-native infrastructure at scale. It offers a high-level declarative language (KCL) and orchestration tools to define, validate, and deploy infrastructure consistently across environments. Kusion brings intelligence to infrastructure planning and execution—flagging configuration drifts, minimizing risks, and accelerating CI/CD workflows. Ideal for large teams managing Kubernetes clusters, multi-cloud systems, or DevSecOps pipelines, Kusion provides both flexibility and governance in one unified stack.
