Nginx Config Generator

The Nginx Config Generator is a free browser-based tool that helps developers and system administrators create correctly formatted Nginx server block configurations without memorizing the complex directive syntax. Nginx is the most widely used web server and reverse proxy in the world, powering over a third of all websites on the internet.

Writing Nginx configurations by hand is error-prone. A single missing semicolon or misplaced directive can cause the server to fail to start. This visual builder eliminates that problem by generating syntactically correct configurations every time. Choose from preset templates for common use cases like static file serving, reverse proxying to Node.js, Python, or Go backends, PHP-FPM with FastCGI, single page application routing, WordPress, load balancing, and HTTPS redirects.

The tool supports full SSL/TLS configuration including certificate paths, protocol selection (TLSv1.2 and TLSv1.3), HTTP-to-HTTPS redirection, and HSTS headers. You can add multiple location blocks with different match types (prefix, exact, regex, priority prefix) and configure each one as a proxy pass, static file server, FastCGI handler, redirect, or try_files fallback. Security headers like X-Frame-Options, Content-Security-Policy, and Referrer-Policy can be toggled on with a single click.

All processing happens entirely in your browser. No data is sent to any server, and no account is required. The generated configuration can be copied to your clipboard or downloaded as a .conf file ready to drop into your /etc/nginx/sites-available/ directory.

1. Optionally select a preset template to start with a common configuration such as Static File Server, Reverse Proxy, PHP-FPM, SPA, WordPress, Load Balancer, or HTTPS Redirect.
2. In the Server tab, enter your domain name, choose a listen port, set the root directory, and configure index files and logging paths.
3. Switch to the SSL/TLS tab to enable HTTPS. Configure certificate and key paths, select TLS protocols, and optionally enable HTTP-to-HTTPS redirect and HSTS.
4. In the Locations tab, configure one or more location blocks. Choose the path, match type, and handler type (proxy_pass, static, FastCGI, redirect, or try_files).
5. For reverse proxy locations, enter the upstream URL and toggle proxy headers and WebSocket support as needed.
6. Open the Advanced tab to enable security headers, gzip compression, and rate limiting with customizable parameters.
7. Review the generated configuration in the output panel on the right, then Copy to clipboard or Download as a .conf file.
