Alternatives to Crossplane
Kubernetes-native framework for building declarative, self-healing control planes
Crossplane ranks #2 of 8 in Infrastructure as Code, with an Alt Score of 81. It is licensed under Apache License 2.0 and open source with paid hosting from Free. 12 of 12 checklist rows are verified against a public source.
Crossplane is an open source framework, hosted by the Cloud Native Computing Foundation, for building cloud native control planes that install directly into a Kubernetes cluster. Teams define custom APIs (Composite Resource Definitions) and Compositions that map declarative desired state to Providers, which continuously reconcile managed resources against external services such as AWS, Azure, and GCP. It is released under the Apache 2.0 license.
Platform engineering teams building self-service, Kubernetes-native control planes for provisioning cloud infrastructure and applications.
A Kubernetes extension installed via Helm that adds Providers (mapping external cloud APIs to managed resources), a Composition engine for building custom APIs, an Operations component for one-off/scheduled tasks, and a package manager for distributing Providers, Functions, and Configurations as OCI images.
Crossplane extends an existing Kubernetes cluster with CustomResourceDefinitions; Provider controllers watch the desired state expressed in those resources and continuously reconcile it against the external service, reverting any out-of-band change back to what is configured in the resource spec.
