You have an app listening on port 3000, a domain pointed at your server, and one remaining job: put HTTPS in front of it. The two names you will see most often are Caddy and Nginx. Both are excellent reverse proxies. The better choice depends less on benchmark charts than on how you want to operate the server.
Caddy: HTTPS as the default
Caddy's standout feature is automatic HTTPS. Give it a public domain with correct DNS and reachable ports 80 and 443, and it obtains and renews certificates for you.
A complete reverse-proxy configuration can be this small:
blog.example.com
reverse_proxy 127.0.0.1:3000
Reload it with:
sudo caddy reload --config /etc/caddy/Caddyfile
That is the entire mental model: domain in, application behind it, certificate handled. Caddy also makes security-conscious defaults easy to keep because you are not maintaining a separate certificate bot and a pile of TLS boilerplate.
For a new VPS, a homelab dashboard, or a handful of small applications, this simplicity is a real operational advantage. Fewer lines mean fewer places to make a mistake at midnight.
Nginx: control and a huge ecosystem
Nginx needs a little more configuration, but it is everywhere. Most teams already have someone who understands it, and its modules, caching controls, load balancing, and documentation cover almost every edge case.
An equivalent site looks like this:
server {
listen 80;
server_name blog.example.com;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
You then add TLS and HTTP-to-HTTPS redirection, commonly with Certbot or another certificate automation tool. Our Nginx reverse proxy guide and Let's Encrypt renewal guide walk through those pieces.
Nginx is a natural choice when you need detailed caching rules, existing include files, specialized modules, or consistency with infrastructure your team already runs.
The comparison that matters
Configuration: Caddy is shorter for common reverse-proxy and static-site setups. Nginx exposes more of the machinery explicitly.
Certificates: Caddy automates HTTPS in its normal configuration path. Nginx usually pairs with a separate ACME client.
Familiarity: Nginx has an enormous installed base and years of examples. Caddy's documentation and Caddyfile are friendly, but unusual requirements may push you toward its JSON configuration or plugins.
Performance: either can serve a typical blog or application without being the bottleneck. Your app, database, TLS termination pattern, caching, and server size usually matter more. Benchmark your own workload before rewriting a working proxy for a theoretical gain.
Operations: Caddy reduces routine certificate work. Nginx rewards teams that want precise control and already have proven configuration management.
A safe migration path
Do not replace a healthy production proxy on a Friday because a comparison article told you to. Test the new configuration on a separate hostname or VM first.
For either proxy:
- Point a test DNS record at the server and wait for it to resolve publicly.
- Allow only the required web ports through the firewall.
- Check proxy headers so the application sees the real scheme and client address.
- Verify certificate renewal, not just the first certificate issuance.
- Test uploads, long requests, WebSockets if used, and redirect behavior.
- Move production only after a rollback path is clear.
My practical recommendation
Choose Caddy for a new, straightforward self-hosted service when automatic HTTPS and a short configuration are the priority. Choose Nginx when existing expertise, advanced routing, or a mature configuration already makes it the easier system to maintain.
The best proxy is not the one with the loudest benchmark. It is the one you can configure correctly, renew automatically, and troubleshoot without dread.
