Rancher

Rancher is a complete open-source Kubernetes management platform that enables enterprises to deploy, manage, and secure multi-cluster Kubernetes environments across data centers, public clouds, and edge infrastructure. The platform provides a unified control plane for provisioning Kubernetes clusters, managing containerized workloads, enforcing security policies, and operating cloud-native infrastructure. Rancher supports multiple Kubernetes distributions including RKE, RKE2, and K3s, and offers enterprise features through Rancher Prime including zero-trust security, advanced policy management, and full lifecycle container management. Acquired by SUSE in 2020, Rancher is widely adopted by organizations running containers in production and has one of the largest Kubernetes open-source communities.
