Reverse Proxy

Forward requests from Nginx to your application server.

HTTPS

Generate SSL-ready server configuration.

Security

Add common HTTP security headers.

What is an Nginx Config Generator?

An Nginx Config Generator creates an Nginx configuration based on your website, application server, domain, ports, SSL requirements, and performance options. Instead of writing every server block manually, you can configure the required options and generate a starting configuration.

Nginx is commonly used as a web server, reverse proxy, load balancer, and gateway in modern web applications. It can sit in front of Node.js, Express, Next.js, React, Python, PHP, and other application servers.

Supported Website Configurations

Nginx Reverse Proxy

Node.js / Express

Next.js Application

React / Vite Website

Static HTML Website

HTTPS / SSL Configuration

WebSocket Applications

Docker Application Proxy

VPS Hosted Applications

Production Web Servers

Nginx Reverse Proxy Example

A reverse proxy receives client requests and forwards them to an application running on another port. For example, your Node.js application can run on port 3000 while Nginx handles incoming HTTP or HTTPS traffic.

server {
    listen 80;
    server_name 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;
    }
}

Using Nginx with SSL

For production websites, Nginx can terminate HTTPS connections using an SSL/TLS certificate. The generated configuration includes placeholders for certificate and private-key paths when SSL is enabled.

Replace the certificate paths with the paths used by your certificate provider or Let's Encrypt setup before deploying the configuration.

Security Features

X-Content-Type-Options header
X-Frame-Options header
Referrer-Policy header
Permissions-Policy header
Configurable client upload size
HTTPS redirect support

How to use this Nginx Config Generator

1. Select the website type. Choose reverse proxy, Node.js, Next.js, React/Vite, or static website.
2. Enter your domain. Provide the domain that will be served by Nginx.
3. Configure your application port. For reverse proxy applications, enter the host and port where your application is running.
4. Enable required features. SSL, WebSockets, gzip, caching, and security headers can be enabled from the settings.
5. Copy or download the configuration. Save the generated configuration as an Nginx configuration file and review it before deployment.

Common Nginx Commands

Command	Purpose
nginx -t	Test the Nginx configuration.
systemctl reload nginx	Reload Nginx configuration.
systemctl restart nginx	Restart the Nginx service.
systemctl status nginx	Check Nginx service status.

Frequently Asked Questions

What is Nginx used for?

Nginx is commonly used as a web server, reverse proxy, load balancer, and HTTP gateway. It can forward requests to applications such as Node.js, Express, Next.js, Python, and PHP.

Can I use this generator for Node.js?

Yes. Select Node.js / Express and configure the application host and port. The generated server block uses proxy_pass and common proxy headers.

Can I generate an Nginx config for Next.js?

Yes. Select Next.js and provide the port where your Next.js application is running, such as port 3000.

Does this automatically install SSL?

No. The generator creates SSL-ready configuration and certificate path placeholders. Certificate installation and certificate management must be configured separately on your server.

Why is proxy_pass used?

proxy_pass tells Nginx where to forward incoming requests. For example, proxy_pass http://127.0.0.1:3000 forwards requests to an application listening on port 3000.

How do I check an Nginx configuration?

Run nginx -t on the server before reloading Nginx. This checks whether the configuration syntax is valid.

Does this generator support WebSockets?

Yes. Enable WebSocket support to add the HTTP/1.1 Upgrade and Connection headers required by many WebSocket applications.

Is the generated configuration production-ready?

It is a useful starting configuration, but you should review SSL certificates, DNS, firewall rules, permissions, upstream health, caching, security headers, logging, rate limiting, and deployment requirements before production use.
