Envoy Gateway

Envoy Gateway is a CNCF project that manages Envoy Proxy as a standalone or Kubernetes-based application gateway. It implements the Kubernetes Gateway API and extends it with its own API group, gateway.envoyproxy.io, whose eight Custom Resource Definitions cover infrastructure shape, client and backend traffic behaviour, security policy, extensibility and direct xDS patching. There is no REST API and no hosted endpoint: the machine-readable contract is the CRD structural schemas plus two first-party gRPC services — an extension server hook and a remote infrastructure provider — that Envoy Gateway calls out to. Apache-2.0 licensed and free, with a published compatibility matrix giving every release a dated end of life, and Gateway API v1.6.1 core and extended conformance certified by report in the standard body's own repository.

Envoy Gateway publishes 3 APIs on the APIs.io network. Tagged areas include API Gateway, CNCF, Envoy, Kubernetes, and Open-Source.

Envoy Gateway’s developer surface includes documentation, API reference, getting-started guide, support, release notes, CLI, authentication, and 26 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/envoy-gateway: open an issue to ask a question, or submit a pull request to add artifacts.
