What should I use to route APIs by header or path?

If you want to route API traffic by header or path, the usual tool is an API gateway or reverse proxy / ingress controller.

Good options

  • NGINX / NGINX Ingress – great for path-based routing, some header-based routing with config
  • Kong – strong API gateway, supports header/path/host routing
  • Traefik – easy dynamic routing, good in container/Kubernetes setups
  • Envoy – very flexible, powerful for advanced routing and service mesh
  • AWS API Gateway / ALB / CloudFront – if you’re on AWS
  • Apigee / Azure API Management / Kong Enterprise – if you need full API management

Rule of thumb

  • Path-based routing like /v1/* vs /v2/*: use an API gateway or ingress
  • Header-based routing like X-Canary: true: use a gateway/proxy that supports header matching
  • Very simple setup: NGINX or Traefik
  • More advanced policies, auth, quotas, observability: Kong or Envoy

Example use cases

  • Route /admin/* to one service and /public/* to another
  • Send requests with header X-Experiment: A to a canary backend
  • Route /api to different versions based on Accept or custom headers

If you tell me your environment—Kubernetes, Docker, AWS, or bare metal—I can recommend the best specific choice.
