Traefik vs Nginx Proxy Manager vs Caddy: Which Reverse Proxy?

A practical 2026 comparison of Traefik, Nginx Proxy Manager, and Caddy — config style, automatic HTTPS, Docker discovery, performance, and GUI — to pick the right homelab reverse proxy.

TL;DR — Pick Nginx Proxy Manager if you’d rather click than edit config, Caddy for the simplest one-file setup with automatic HTTPS, and Traefik if you run lots of Docker services and want the proxy to configure itself from container labels.

Once your homelab runs more than a couple of services, you stop wanting to remember 10.0.0.20:3000 and start wanting grafana.homelab.lan with a padlock. That’s a reverse proxy, and the three names you’ll weigh are Traefik, Nginx Proxy Manager (NPM), and Caddy. All three are free, open source, and give you automatic HTTPS — the real difference is how you tell them what to do.


The short answer

  • Pick Nginx Proxy Manager if you’d rather click than edit config — it’s a friendly web GUI and the gentlest on-ramp.
  • Pick Caddy if you want the simplest possible setup: one small text file, HTTPS on by default.
  • Pick Traefik if you run lots of Docker services and want the proxy to configure itself from container labels.

All three are free, open source, and do automatic Let's Encrypt certificates. The real split is the configuration philosophy: labels vs GUI vs a single file.

The one thing that actually decides it: configuration philosophy

Everything else follows from how each expects you to define routes.

  • Traefik — the app describes itself. You add a few labels to a Docker container and Traefik discovers it and starts routing instantly, no reload. The proxy config effectively maintains itself as you add and remove services. That’s a superpower on a busy Docker host and overkill on a static setup. It also reads two kinds of config (a static file at startup for entrypoints/certs, and dynamic routes from labels) — a concept worth understanding, covered in What Is Traefik?.
  • Nginx Proxy Manager — you click. NPM is a web UI on top of nginx: add a “Proxy Host,” point it at an internal address, tick SSL → Request a new certificate, done. Nothing to templatize, nothing to reload by hand. It’s the friendliest for people who don’t want YAML in their life, and it’s genuinely fast because nginx is doing the work underneath.
  • Caddy — one file. A Caddyfile is about as terse as config gets: a hostname, a reverse_proxy line, and HTTPS is handled automatically. No GUI, no discovery — just a file you can read at a glance and keep in version control.
The honest tie-breaker

If you add/remove Docker services weekly, Traefik saves you the most over time. If you set up a handful of services and rarely touch them, Caddy (one file) or NPM (one GUI) is less to think about. There’s no wrong answer — pick the workflow you’ll actually enjoy.


Automatic HTTPS — a wash, with nuances

All three get you free, auto-renewing Let’s Encrypt certificates, so the padlock isn’t a deciding factor. The nuances:

  • Caddy turns HTTPS on with zero configuration — it’s the whole design ethos.
  • Traefik needs a certificate resolver defined once in static config; after that every service gets a cert automatically (and it’s the easiest of the three to issue a wildcard via the DNS-01 challenge).
  • NPM does it per-host in the UI, including DNS-challenge wildcards, with a couple of clicks.

For an internal-only lab where services have no public port, all three can use the DNS challenge to get trusted certs — pair any of them with Pi-hole local DNS so the names resolve on your LAN.


Performance — real, but rarely your bottleneck

In 2026 community benchmarks, NPM/nginx is fastest on raw requests per second, Caddy is a close second, and Traefik trails on throughput and P95 latency. (reverse-proxy showdown 2026) Be honest with yourself about scale, though: at homelab traffic levels none of these is the bottleneck — your upstream app and your internet link are. Choose on workflow and features, not benchmark charts, unless you’re genuinely serving heavy public traffic.


Security & extras

  • Traefik has a rich, composable middleware chain — auth, rate limits, IP allow-lists, headers — applied per-router. Mind the Docker-socket exposure (mount it read-only or via a socket proxy).
  • NPM exposes nginx access lists and custom directives via an advanced tab, and the community fork NPMplus adds HTTP/3, CrowdSec, and ModSecurity if you want a hardened variant. (NPMplus)
  • Caddy stays minimal by default; extras come from plugins you compile in with xcaddy (e.g. Crowdsec, extra DNS providers).

Whichever you choose, a reverse proxy complements a firewall and VPN — it shrinks and centralizes your attack surface but doesn’t replace them.


Who should pick what

  • New to this, or you just want a UI: Nginx Proxy Manager. Click to add a host, tick for HTTPS, move on.
  • You value simplicity and version-controlled config: Caddy. One readable file, HTTPS for free.
  • You run a Docker-heavy lab and add services constantly: Traefik. Label a container and it’s routed — the config maintains itself.
  • You want a hardened NPM: look at NPMplus.

They’re not hard to migrate between, either — the concepts (a hostname → an internal address, plus a certificate) are the same everywhere. Start with whichever fits how you like to work; you can always switch once you know what you actually want.
