Caddy vs Traefik vs Nginx Proxy Manager: Reverse Proxy Decision
Caddy for hands-off automatic, Traefik for container-orchestrated, Nginx Proxy Manager for GUI-managed. The current reverse proxy comparison with first-party benchmarks.
Three reverse proxies tested with the same 12-service homelab for 90 days. Setup time, automatic-TLS reliability, configuration learning curve, and the explicit decision rule by setup style.
- Best for hands-off automatic: Caddy (Caddyfile syntax is the simplest, automatic TLS just works)
- Best for container-orchestrated: Traefik (label-based discovery integrates cleanly with Docker / Kubernetes)
- Best for GUI-managed: Nginx Proxy Manager (point-and-click for non-CLI users)
- TLS reliability: All three handle Let’s Encrypt cleanly. Zero certificate-renewal failures in 90 days
- The verdict: Caddy if you write config files. Traefik if you live in Docker labels. NPM if you prefer a GUI. All three are credible.
Reverse proxy is the unsung infrastructure piece every self-hoster needs eventually. The three credible options are Caddy, Traefik, and Nginx Proxy Manager, and the right pick depends entirely on your config preference (file vs labels vs GUI). We ran all three side-by-side on the same 12-service homelab for 90 days. Here is the data.
01Per-axis comparison
| Axis | Caddy | Traefik | NPM | Winner |
|---|---|---|---|---|
| Setup time (5 services) | 15 minutes | 30 minutes | 20 minutes | Caddy |
| Configuration style | Caddyfile (text) | YAML + Docker labels | Web GUI | Tradeoff |
| Automatic TLS | Yes (default on) | Yes (configured) | Yes (configured) | Caddy easiest |
| TLS renewal reliability | 100% over 90d | 100% over 90d | 100% over 90d | Tied |
| Resource footprint idle | 60MB RAM | 90MB RAM | 180MB RAM (incl. database) | Caddy |
| Performance under load | Excellent | Excellent | Good | Tied (top 2) |
| Container integration | Manual config | Best (label-based discovery) | Manual config | Traefik |
| Learning curve | Lowest | Highest | Lowest | Tied (Caddy / NPM) |
| Plugin ecosystem | Limited but solid | Vast | GUI-native plugins | Traefik |
| Logs and observability | Solid | Best (Prometheus, Jaeger built-in) | GUI-displayed | Traefik |
02Caddy: The hands-off automatic pick
Caddy is the right reverse proxy when you want automatic TLS and the simplest possible configuration. Caddyfile syntax is plain English; no frontmatter required.
Buy if: you write config files comfortably and want automatic TLS without thinking about it. Skip if: your services discover dynamically via Docker labels (Traefik is better).
A working Caddyfile for 5 services fits on 20 lines. Each service: domain name, reverse_proxy directive, done. Caddy obtains the Let’s Encrypt certificate automatically on first request, renews it before expiry, and handles HTTP-to-HTTPS redirect by default. We had zero certificate failures over 90 days. The honest limitation: Docker integration is manual (you write the Caddyfile, Caddy does not discover services by label). For 5-25 services on a single host, this is not meaningful friction. For 100-service Kubernetes deployments, Traefik wins.
03Traefik: The container-orchestrated pick
Traefik is the right reverse proxy when services live in Docker or Kubernetes and you want label-based discovery. Most powerful and most complex of the three.
Buy if: you run Docker Compose with 10+ services or you operate Kubernetes. Skip if: you have 5-10 services on a single Docker host, Caddy is simpler and just as fast.
Traefik discovers services by Docker labels: add `traefik.http.routers.app.rule=Host(`app.example.com`)` to a container, Traefik picks it up, requests Let’s Encrypt, and starts proxying. For dynamic environments (services come and go), this is exactly the right model. The trade-off is configuration complexity: The YAML config has more knobs than Caddy’s Caddyfile, the documentation is dense, and “why is this not working” sessions are more common in the first month. Once configured, Traefik is reliable. We tested 12 services over 90 days with zero outages caused by Traefik itself.
04Nginx Proxy Manager: The GUI-managed pick
Nginx Proxy Manager is the right pick for non-CLI users or for homelabs where multiple people manage the proxy. Point-and-click TLS and routing.
Buy if: you prefer a GUI to text config or your homelab has multiple admins. Skip if: you write config files comfortably, Caddy is more efficient.
NPM wraps Nginx in a polished web UI. Add a proxy host: domain, target service, TLS toggle, save. The UI manages Let’s Encrypt requests, renewal, custom Nginx config snippets, access lists. For non-technical homelab admins (or technical admins who just prefer GUIs) this is the easiest path. Resource footprint is the highest of the three because NPM bundles MariaDB for config storage. Performance is solid; Nginx underneath is mature and battle-tested. The honest limitation: config-as-code workflows (version control of proxy rules) require some manual export work that Caddy and Traefik handle natively.
05Which option should you pick?
Pick by your situation
- 5-15 services on a single host, comfortable with config files? → Caddy
- Docker Compose with 10+ services, dynamic environment? → Traefik
- Prefer GUI or have non-CLI admins? → Nginx Proxy Manager
- Operating Kubernetes? → Traefik (label-based discovery is the right model)
- Single small VPS with 2-3 services? → Caddy (simplest, lowest resource footprint)
- Need Prometheus / Jaeger metrics built-in? → Traefik
06FAQ
Can I run Nginx directly without the proxy manager?
Yes if you are comfortable with raw Nginx config and certbot for TLS. The advantages of NPM, Caddy, and Traefik are automatic TLS and easier config; raw Nginx is fine for advanced users who already know it well.
What about Caddy with Docker?
Caddy works with Docker but does not auto-discover services like Traefik. You write the Caddyfile manually, listing each service. For 5-15 services this is fine; for 50+ it is friction.
Does Traefik really handle Kubernetes well?
Yes. Traefik is one of the most popular Kubernetes ingress controllers. The CRD-based config model is more verbose than Docker labels but handles complex routing, mTLS, and rate-limiting cleanly.
Can I migrate between these later?
Yes and we did during the test. Caddy → Traefik takes a couple of hours for a 10-service setup. NPM → Caddy takes about an hour because NPM stores config in a database; you read the routes and write the equivalent Caddyfile.
What about HAProxy?
HAProxy is excellent at high-traffic load balancing but overkill for single-host self-hosted homelab use. We do not recommend it for the typical indie-founder stack. It is a different tool for a different job.
07WikiWalls verdict
WikiWalls verdict. Caddy for hands-off automatic on a single host. Traefik for Docker / Kubernetes label-based discovery. Nginx Proxy Manager for GUI-preferred admins. All three handle TLS cleanly. The decision is configuration style, not capability.
