Envoy Gateway vs Traefik Hub API Gateway

Envoy Gateway is a free, open-source application gateway for managing Envoy Proxy in standalone or Kubernetes-based deployments. It provisions and configures proxies through Kubernetes Gateway API resources, extending the API to expose Envoy features. Traffic management includes rate limiting, retries, circuit breaking, timeouts and failover. Security options include mTLS, JWT-based access control, OIDC integration and API-key authorization; listed authentication methods also include Basic Auth and external authorization. Envoy Gateway supports TLS termination and can attach an OCSP response from a Gateway certificate Secret during a TLS handshake. Metrics, access logging and distributed tracing are among its observability features. Installation options include Helm, Argo CD, Flux CD and Kubernetes YAML, though the quickstart requires a Kubernetes cluster. The project lists HTTP, HTTPS, gRPC, TLS, TCP and UDP support. Integrations and ecosystem projects include Envoy AI Gateway, Kuadrant, Knative, KServe and KEDA. Community help is directed through Envoy Slack, GitHub discussions and issues, and community meetings. Documentation cautions that the latest release includes recent main-branch commits and might not be stable.

Traefik Hub API Gateway is a hybrid gateway for managing and securing APIs and microservices. It discovers services and adjusts routing when services are deployed or removed, with Kubernetes service discovery, Helm charts, Gateway API, and declarative configuration through Kubernetes resources and CRDs. It supports HTTP, HTTP/2, TCP, UDP, WebSockets, and gRPC, alongside rate limiting, request transformation, HTTP caching, canary deployments, and graceful configuration reloads.

Security options include JWT, OAuth2, OIDC, LDAP, API keys, HMAC, and Open Policy Agent, as well as TLS management and a Web Application Firewall powered by OWASP Coraza. The feature matrix lists FIPS 140-3 compliance. API management includes an inventory, versioning, plans and bundles, subscriptions, and a developer portal with interactive testing and access-credential generation. GitOps tools such as Flux and Argo are supported. The product is stateless and horizontally scalable, and integrates with HashiCorp Vault and OpenTelemetry. It is intended for DevOps and Platform Engineering teams. Pricing is available on request; there is no free plan, though a free trial is offered without a stated duration.
