What kgateway is

kgateway is a Kubernetes-native ingress controller and API gateway control plane. It configures an Envoy data plane through the Kubernetes Gateway API and is a free, self-hosted project for Linux environments. Its documented traffic tools include routing and aggregation, load balancing, rate limiting, traffic splitting, and request transformations. Security capabilities include TLS and mTLS, external authentication, API keys, JWT, OAuth2/OIDC, and IP access control. For resilience, the project lists circuit breakers, fault injection, retries, timeouts, and outlier detection. Integrations include Istio, AWS load balancers, Argo Rollouts, ExternalDNS, cert-manager, and OpenTelemetry. The control plane installs in a Kubernetes cluster through Helm or Argo CD. The project launched in 2018 as Gloo, originally created by Solo.io, and is a Cloud Native Computing Foundation sandbox project. Solo offers free community support through Gloo Community and a public GitHub repository. The project describes use cases in security, traffic management, and resilience, spanning lightweight microgateways between services through centralized gateways handling billions of API calls. Its documentation directs readers seeking AI, MCP, or LLM connectivity to the separate Agentgateway project.
