Nginx Config Generator

What is Nginx Config Generator?

Nginx Config Generator creates production-ready Nginx server block configurations for common use cases including reverse proxy, single-page application (SPA) routing, static file serving, load balancing, and SSL/TLS termination. It generates proper configurations with security headers, gzip compression, rate limiting, and Let's Encrypt SSL settings. Each generated config includes inline comments explaining the directives.

DevOps engineers configuring web servers, backend developers setting up reverse proxies, and system administrators managing production Nginx deployments. The tool runs entirely in your browser — your data never leaves your device.

How to Use Nginx Config Generator

1. Select the server type — reverse proxy, SPA, static files, or load balancer
2. Enter your domain name and upstream application server address and port
3. Toggle SSL/TLS settings with Let's Encrypt certificate paths and modern cipher configuration
4. Enable optional features — gzip compression, security headers, rate limiting, and access logging
5. Copy the generated Nginx configuration to your sites-available directory

Common Use Cases

• Configuring Nginx as a reverse proxy for a Node.js or Python application server
• Setting up SPA routing that serves index.html for all client-side routes (try_files)
• Generating SSL/TLS configuration with modern cipher suites and HSTS headers
• Creating load balancer configurations for distributing traffic across multiple upstream servers
• Setting up static file serving with proper caching headers for CDN-like performance

Pro Tips

• For SPAs, the key directive is try_files $uri $uri/ /index.html — this tells Nginx to try serving the requested file first, then fall back to index.html for client-side routing
• Set proxy_set_header X-Forwarded-For and X-Real-IP when using Nginx as a reverse proxy — without these, your application sees all requests as coming from the Nginx server's IP
• Enable gzip_vary on and gzip_proxied any to ensure that both direct and proxied responses are compressed — this is often missed and causes poor compression in CDN-backed setups
