Spring Cloud Gateway vs Traefik Hub API Gateway

Spring Cloud Gateway has no write-up on Specifiction yet; its figures are above.

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.
