Caddy vs Nginx vs Traefik: Reverse Proxy Comparison

Your reverse proxy is the front door to all your self-hosted apps. Compare Caddy, Nginx, and Traefik to choose the right one.

What Does a Reverse Proxy Do?


A reverse proxy sits in front of your applications and:

  • Routes requests to the correct app based on domain name
  • Terminates SSL/TLS (HTTPS)
  • Load balances across multiple instances
  • Adds security headers
  • Caches static content

    • Caddy


    Strengths

  • Automatic HTTPS (zero configuration SSL via Let's Encrypt)
  • Simplest configuration of any reverse proxy
  • HTTP/2 and HTTP/3 by default
  • Single binary, no dependencies
  • Caddyfile is human-readable

    • Configuration

    app.example.com {

    reverse_proxy localhost:3000

    }


    That's it. SSL is automatic.


    Weaknesses

  • Smaller ecosystem than Nginx
  • Less battle-tested at extreme scale
  • Fewer third-party modules

    • Nginx


    Strengths

  • Powers ~30% of the internet
  • Extremely well-documented
  • Massive ecosystem
  • Proven at massive scale
  • Every hosting tutorial uses it

    • Configuration

    server {

    listen 443 ssl;

    server_name app.example.com;

    ssl_certificate /path/to/cert;

    ssl_certificate_key /path/to/key;

    location / {

    proxy_pass http://localhost:3000;

    }

    }


    Plus SSL certificate management (certbot), HTTP/2 config, security headers...


    Weaknesses

  • Manual SSL certificate management
  • Verbose configuration
  • Reload required for config changes
  • No native HTTP/3 support until recently

    • Traefik


    Strengths

  • Automatic service discovery (Docker labels)
  • Built for containers and orchestrators
  • Dashboard for monitoring
  • Middleware system (auth, rate limiting, etc.)
  • Automatic SSL

    • Configuration

    Defined via Docker labels on containers:

    labels:

  • traefik.http.routers.myapp.rule=Host(`app.example.com`)

    • Weaknesses

  • Complex configuration for advanced setups
  • Higher resource usage than Caddy/Nginx
  • Steeper learning curve
  • YAML/TOML configuration can be confusing

    • Recommendation


  • Self-hosting beginners: Caddy (simplest, auto SSL)
  • Docker-heavy setups: Traefik (auto-discovery)
  • Maximum control/scale: Nginx

    • TinyPod uses Caddy. Auto HTTPS, minimal configuration, and rock-solid reliability.
