Crossplane

Crossplane is a graduated CNCF open-source Kubernetes add-on that transforms a cluster into a universal control plane for cloud infrastructure, services, and applications. Crossplane introduces custom resources including CompositeResourceDefinitions (XRDs), Compositions, Claims, Providers, ProviderConfigs, Configurations, Functions, and EnvironmentConfigs, allowing platform teams to author self-service platform APIs that compose managed resources across AWS, GCP, Azure, and other providers using Kubernetes-style declarative configuration.

Crossplane publishes 7 APIs on the APIs.io network, including CompositeResourceDefinitions API, Compositions API, Configurations API, and 4 more. Tagged areas include Apache 2.0, CNCF, Cloud-Native, Composition, and Control Plane.

The Crossplane catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Crossplane’s developer surface includes authentication, documentation, getting-started guide, engineering blog, changelog, and 21 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/crossplane: open an issue to ask a question, or submit a pull request to add artifacts.
