Open-source feature management platform
Meshery, the cloud native manager
vCluster creates tenant clusters: fully isolated environments delivered as managed Kubernetes, or as the foundation for Slurm, Ray, Run:ai and inference clusters. Each gets its own API server, CRDs and RBAC, and runs on an existing cluster or standalone on bare metal. CNCF Certified Kubernetes.
Rainbond is an open-source container platform that requires no Kubernetes expertise. Its core capabilities are 100% open source. It abstracts away infrastructure complexity and provides a unified way to deploy and manage business applications, AI-generated projects, open-source AI software, and large language model services. AI helps teams deploy
