About Nginx Config Generator

The Nginx Config Generator is a free online tool that creates production-ready Nginx server block configurations through an intuitive visual interface. Nginx is the world's most popular high-performance web server, reverse proxy, and load balancer, powering millions of websites and applications worldwide. Proper configuration is critical for security, performance, and reliability, but the syntax can be complex and error-prone.

This generator eliminates the need to memorize Nginx directives by letting you toggle features with switches and fill in values with labeled form fields. It produces clean, well-commented nginx.conf server blocks that include SSL/TLS setup with HTTP-to-HTTPS redirection, gzip compression, security headers, static file caching, reverse proxy configuration with WebSocket support, and custom location blocks.

Whether you are deploying a static website, a Node.js application, a Python/Django backend, or a PHP project, this tool generates the right configuration in seconds. Copy it to your clipboard or download it as a .conf file, then drop it into your Nginx sites-available directory and reload. The entire tool runs in your browser with no server-side processing.

Gzip compression with optimized MIME type list and compression level
Static file caching for images, CSS, JS, and fonts with configurable max-age
Reverse proxy setup with proxy_pass, proper headers, and optional WebSocket support
Custom location blocks with proxy_pass, try_files, and return directives
One-click copy to clipboard and .conf file download
Live preview that updates instantly as you change settings
Well-commented output with attribution link for easy team sharing

How to Use

Set server basics: Enter your domain name, listen port, and document root directory in the Server Configuration section.
Enable SSL: Toggle SSL/HTTPS on and provide the paths to your SSL certificate and private key. The tool auto-generates an HTTP-to-HTTPS redirect block.
Toggle features: Enable gzip compression, security headers, and static file caching using the feature switches. Adjust cache max-age as needed.
Configure reverse proxy: If your app runs on a backend server, enable Reverse Proxy, enter the upstream URL, and optionally enable WebSocket support.
Add custom locations: Click "Add" to create additional location blocks with proxy_pass, try_files, or return directives for specific URL paths.
Copy or download: Review the generated configuration in the live preview, then click "Copy" to copy to your clipboard or "Download" to save as a .conf file.

Use Cases

Static website hosting: Generate a config for serving HTML, CSS, and JavaScript files from a document root with gzip compression and caching.
Node.js application proxy: Set up Nginx as a reverse proxy in front of Express, Next.js, or Nuxt.js applications running on localhost ports.
SSL/HTTPS migration: Create a complete SSL configuration with certificate paths, strong cipher suites, and automatic HTTP redirect in minutes.
Security hardening: Enable a full set of security headers (HSTS, CSP, X-Frame-Options) to protect against XSS, clickjacking, and MIME sniffing attacks.
WordPress & PHP hosting: Configure Nginx with try_files for clean URLs and proxy or FastCGI pass for PHP processing.
Microservices routing: Use custom location blocks to route different URL paths to different backend services running on separate ports.
DevOps & CI/CD: Generate config files as part of deployment pipelines and include them in infrastructure-as-code repositories.
Learning Nginx: Explore how different settings translate into Nginx directives by toggling features and reading the well-commented output.

Frequently Asked Questions

Is this tool free?

Yes. The Nginx Config Generator is completely free to use with no account required, no limitations, and no hidden costs.

Is my data secure?

All configuration generation happens entirely in your browser. Your domain names, paths, and settings are never sent to any server or stored anywhere.

Can I use the generated config in production?

Yes. The configurations follow Nginx best practices and are suitable for production use. Always run "nginx -t" to validate syntax before reloading your server.

Do I need to install anything?

No. The tool runs in your browser. You only need Nginx installed on your server to use the generated configuration file.

Does it support Let's Encrypt certificates?

Yes. Enter the certificate and key paths provided by Let's Encrypt (typically /etc/letsencrypt/live/yourdomain/fullchain.pem and privkey.pem) in the SSL fields.

Can I add multiple location blocks?

Yes. Click the "Add" button in the Custom Location Blocks section to add as many location blocks as you need, each with its own path, directive, and value.

Tips & Best Practices

Always test before reloading: Run "nginx -t" to validate your configuration syntax before applying changes with "nginx -s reload" to avoid downtime.
Use TLS 1.2+ only: Disable older protocols (SSLv3, TLS 1.0, TLS 1.1) to protect against known vulnerabilities. The generator enforces TLS 1.2 and 1.3 by default.
Enable gzip for text-based content: Compressing HTML, CSS, JavaScript, and JSON can reduce transfer sizes by 60-80%, significantly improving load times.
Set appropriate cache durations: Use longer cache times (30+ days) for versioned static assets and shorter times for frequently updated content.
Limit exposed server information: Avoid revealing your technology stack through Server or X-Powered-By headers. Consider adding "server_tokens off;" to your main nginx.conf.
Monitor access and error logs: The generated config includes logging directives. Regularly review logs for unusual traffic patterns, errors, and security incidents.
