How to use Nginx Configuration Generator

Get the best out of Nginx Configuration Generator: every option explained, a worked example, and what to check when the output is not what you expected.

Updated July 31, 2026

What it does

Interactively generate clean, production-ready Nginx server configurations. It runs entirely in your browser — your input never leaves your device.

Options

Every setting this tool exposes, straight from the code that validates it.

OptionTypeDefaultWhat it does
domaintextexample.comDefaults to example.com.
typeone of: proxy, staticproxyDefaults to proxy.
targettexthttp://127.0.0.1:3000Defaults to http://127.0.0.1:3000.
rootPathtext/var/www/example.com/htmlDefaults to /var/www/example.com/html.
maxBodytext50MDefaults to 50M.
ssltrue / falsetrueDefaults to true.
http2true / falsetrueDefaults to true.
gziptrue / falsetrueDefaults to true.
securityHeaderstrue / falsetrueDefaults to true.
corstrue / falsefalseDefaults to false.

Worked example

Run these settings on the tool page:

  • domain: example.com
  • type: proxy
  • target: http://127.0.0.1:3000
  • rootPath: /var/www/example.com/html
  • maxBody: 50M
  • ssl: true
  • http2: true
  • gzip: true
  • securityHeaders: true
  • cors: false

You get:

# Nginx Server block configuration for example.com

server {
    listen 80;
    server_name example.com www.example.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    server_name example.com www.example.com;

    # SSL Certs (Let's Encrypt / Certbot path)
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

    # Modern secure protocols
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;

    # Main server settings
    client_max_body_size 50M;
    root
… (truncated)

Getting the result you want

Most of the control here is in the options above. If the output is not what you expected, the setting to check first is domain and type — those change the shape of the output rather than the input it accepts.

Troubleshooting

  • It is slow on very large input. Everything runs in your browser, so speed depends on your device. Very large inputs are best split up, or run through the API where the work happens on our servers.

Automating it

The same logic is available as a REST endpoint, so you can run it from a script, a CI job or your own app.

Bash
curl "https://api.toolsxpo.com/v1/nginx-config-generator" \
  -H "Authorization: Bearer $TOOLSXPO_KEY"

It costs 1 credit per successful call. See the full endpoint reference, or try it in the playground.
