Final Verdict

Related Caddy is the better choice for most self-hosters. Its Caddyfile syntax is dead simple, automatic HTTPS works out of the box with zero configuration, and it uses far less memory than Traefik. Choose Traefik if you need Docker label-based auto-discovery so new containers are routed automatically, if you run Docker Swarm or Kubernetes, or if you need advanced middleware like circuit breakers and rate limiting. Traefik (v3.6) is a cloud-native edge router written in Go. It watches Docker, Kubernetes, and other providers for service changes and automatically creates routes based on labels. Configuration is split between a static config file and dynamic config via labels or files. Traefik has been around since 2016 and is widely used in production orchestration environments. Caddy (v2.9) is a modern web server and reverse proxy written in Go. Its defining feature is automatic HTTPS — point it at a domain name and it handles certificate provisioning and renewal without any configuration. Routes are defined in a Caddyfile, a human-readable config format that replaces Nginx's verbose blocks with minimal syntax. Both are Go binaries, both handle automatic Let's Encrypt, and both reverse proxy your self-hosted services. The difference is in how you configure them and what happens when you add a new service. Caddy is simpler to set up. A single Docker Compose service, two port mappings, two volumes, and a Caddyfile that reads like English. To proxy a service: That's it. HTTPS is automatic. No static config, no entry points, no certificate resolvers. Traefik requires more initial setup. You need a static configuration file defining entry points, certificate resolvers, and providers. Then each service needs Docker labels specifying the router rule, entry point, and TLS resolver. The learning curve is steeper, but the payoff is that new containers with the right labels are discovered automatically — no config file editing needed. For a homelab with 5-15 services that change occasionally, Caddy's simplicity wins. For a dynamic environment where containers come and go frequently, Traefik's auto-discovery is worth the upfront complexity. Caddy is significantly lighter. For a homelab running on a mini PC or Raspberry Pi, this matters. Traefik's higher memory footprint comes from its service discovery watchers and middleware pipeline. Both handle typical self-hosting traffic loads without breaking a sweat — the difference only matters when resources are constrained. Both have strong communities. Traefik's documentation is thorough but sometimes hard to navigate — the split between static and dynamic config across multiple providers creates many pages. Caddy's documentation is notably well-organized and its Caddyfile examples are easy to follow. Not natively. There are community plugins like caddy-docker-proxy that add Docker label-based configuration to Caddy, but it is a third-party solution and not as mature as Traefik's native provider. Both are fast enough for any self-hosting workload. In synthetic benchmarks, Caddy and Traefik perform comparably. The bottleneck in a homelab is always the backend service, never the reverse proxy. Routes don't transfer directly. Traefik uses labels and YAML; Caddy uses the Caddyfile. But both use Let's Encrypt, so certificate migration is not needed — the new proxy will obtain fresh certificates automatically. Caddy wins for most self-hosters. It is simpler to configure, uses less memory, starts faster, and its automatic HTTPS is genuinely zero-config. The Caddyfile is readable by anyone, and adding a new service takes two lines. Traefik is the better tool if your workflow is container-centric and you want routing defined alongside your Compose files via labels. It is also the clear choice for Swarm and Kubernetes deployments. But for the typical self-hoster running a fixed set of services on a single server, Caddy's simplicity is a real advantage that Traefik's power does not overcome.
