Envoy Gateway vs Tencent Cloud 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.

Tencent Cloud API Gateway manages APIs from creation and testing through release, operation, and deactivation. It supports HTTP and HTTPS, with testing, staging, and production environments, versioning, and rollback. Users can set per-second call limits and monitor request counts, outbound public traffic, response times, and frontend and backend errors. HMAC key-pair authentication uses keys issued by the gateway, and SSL certificates secure data transfer at the API frontend. APIs can be published as purchasable products through API Market, and the service integrates with Tencent Cloud SCF and COS. Dedicated instances connect to VPC and Direct Connect, while shared instances cannot connect to VPC. Shared instances support requests up to 16 MB and 500 QPS per service; requests may be discarded at the QPS limit. New users receive a first-year monthly allowance of one million calls and 1 GB of public outbound traffic, with unused monthly allowance not carried forward. The service is cloud-deployed and available through web and API platforms. Its listed pricing note is From $1.90/mo; a separate paid-from value is 0.4 /mo. The shared-instance plan lists free, with excess calls and outbound traffic pay-as-you-go.
