A Modern Alternative to Gravitee
Kgateway is an open source API gateway built on Envoy and the Kubernetes Gateway API standard, rather than Gravitee's Java runtime and event-native management plane. Compare it with Gravitee before you choose.

Why Teams Choose Us
“Gravitee’s Java runtime needs real memory and JVM warm-up time before it performs well.”
Kgateway runs on Envoy, a lightweight proxy with no JVM warm-up, so gateway instances reach full performance immediately after startup.
“Gravitee’s Console, Gateway, and Alert Engine are separate components we have to deploy and keep in sync.”
Kgateway is a single Kubernetes-native gateway configured through the Kubernetes Gateway API standard, so there’s no separate management console or alerting component to run alongside it.
“We want an open source gateway with a standard config model, not a vendor-specific one.”
Kgateway is open source and CNCF-hosted, built on the Kubernetes Gateway API standard rather than a Gravitee-specific configuration model, so what your team learns stays portable.

Frequently Asked Questions
How is kgateway different from Gravitee?
How is kgateway different from Gravitee?
Gravitee runs on a Java runtime with its own event-native management plane for Kafka, MQTT, and webhooks. Kgateway is built on Envoy and the Kubernetes Gateway API standard, with a lighter footprint and no JVM warm-up time.
Do I need Gravitee’s API Management Console or Alert Engine with kgateway?
Do I need Gravitee’s API Management Console or Alert Engine with kgateway?
No. Kgateway is a single Kubernetes-native gateway configured through the Kubernetes Gateway API standard, without a separate management console, alert engine, or access-management component to deploy and maintain.
Is kgateway open source, like Gravitee?
Is kgateway open source, like Gravitee?
Yes. Kgateway is open source and CNCF-hosted, free to run on your own, with enterprise support and advanced policy available on top when you need production SLAs.
Does kgateway support event-driven protocols like Gravitee does?
Does kgateway support event-driven protocols like Gravitee does?
Kgateway focuses on HTTP and gRPC traffic through Envoy and the Kubernetes Gateway API. If Kafka, MQTT, or webhook management across a unified event plane is your primary need, that's a specific strength of Gravitee's platform worth weighing against kgateway's Kubernetes-native approach.
What does it cost to run kgateway versus Gravitee?
What does it cost to run kgateway versus Gravitee?
Both have an open source core, so cost comes down to infrastructure footprint and support tier. Kgateway's Envoy-based architecture avoids the JVM memory and warm-up overhead of Gravitee's Java runtime. A demo is the fastest way to get numbers scoped to your environment.
