Crossplane vs Electros

Crossplane is a free, open-source CNCF framework for building control planes that manage cloud-native software. Its Composition feature lets teams define custom APIs with pipelines of functions instead of maintaining controllers. Managed resources are Kubernetes custom resources that can represent external services such as AWS RDS instances. Community providers cover AWS, Azure, Google Cloud, Kubernetes, GitHub, GitLab and Argo CD, among others. A package manager installs managed resources and composition functions and can distribute configurations across control planes. Crossplane installs into an existing Kubernetes cluster with a Helm chart; the guide requires an actively supported Kubernetes version and Helm v3.2.0 or later. Operations support one-time, scheduled and resource-change-triggered pipelines, but are marked alpha in Crossplane v2. The framework uses Kubernetes RBAC. Its default crossplane-admin ClusterRole has full access to secrets and namespaces and can bind roles to other entities. The project is Apache 2.0 licensed and identifies as vendor neutral.

Electros is a Metacloud control plane for governing public, private, and sovereign clouds and hypervisors from one interface without replacing existing infrastructure. Teams state infrastructure requirements as cloud intents, and Electros composes governed infrastructure to meet them. It provides a GUI, CLI, and API, alongside cross-provider orchestration, centralized observability, and cost visibility. Atomosphere maps AWS, Azure, Google Cloud, and more than 10 other cloud providers across more than 235 data centers, with real-time cloud cost comparison. Atomosquare connects VMware, Proxmox, Hyper-V, and private clouds. Electros communicates with infrastructure through Elemento’s C4 interoperability protocol and underlying fabrics. The product describes AtomOS as a free, RHEL-compatible KVM hypervisor with GPU passthrough, autonomous clustering, and unlimited VMs. Desktop installers are available for Linux, macOS, and Windows 10/11. Start costs €199 a month, billed annually, for up to 7 active connections; Grow costs €399 a month, billed annually, for up to 15. A 7-day trial is listed.
