Google Cloud Endpoints vs Traefik Hub API Gateway

Google Cloud Endpoints manages APIs with tools for securing access, monitoring activity, analyzing usage, and setting quotas. It supports API descriptions written in OpenAPI 2.0 or 3.x, as well as gRPC, and provides management through ESP or ESPv2. Documented deployment backends include Google Kubernetes Engine, Compute Engine, Kubernetes, App Engine, Cloud Run, Cloud Run functions, and Knative serving; proxy availability varies by backend. Endpoints is optimized for Docker and can host an API wherever Docker runs, provided it has internet access to Google Cloud. API keys can be required and validated to identify a Google Cloud project for quotas, billing, and monitoring. Documented user authentication options include Firebase Authentication and Auth0, using JWT validation by ESP. Logs and metrics are viewable in the Google Cloud console. Pricing depends on API calls and Service Control calls: the Free usage tier is free for 1,999,999 calls; Standard is $3 a month for 2,000,000 to 1,000,000,000; and High-volume is $1.50 a month for 1,000,000,000 and above. Listed rates are per million API calls.

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.
