Traefik

Traefik is a modern reverse proxy that auto-discovers services. v3.0 (2025) supports Wasm Plugins and the Kubernetes Gateway API.

When to Use

• Docker/K8s: It watches the Docker socket or K8s API and reconfigures itself automatically. No config file edits needed for new services.
• Ease of Use: Automatic Let's Encrypt (ACME) integration is best-in-class.
• Middleware: Built-in auth (Basic, ForwardAuth), rate limiting, and circuit breakers.
