What does this tool do?
The Nginx Config Generator builds a ready-to-use Nginx server block from your domain and chosen mode. It supports reverse proxy, static file serving and SPA (React/Vue) modes, and you can add SSL, Gzip and a www redirect with a single click. It saves time for developers and sysadmins setting up servers.
How to use it
- Enter your configuration details.
- Review the generated output.
- Copy the ready-to-use code or file.
Three deployment scenarios
The mode selector tailors the config to your use case. Proxy mode generates a location block that forwards to an app on the port you specify and handles WebSocket upgrades. Static mode adds a root directory, try_files, and 30-day cache headers for images and assets. SPA mode falls every request back to index.html for client-side routing and caches assets as immutable for a year. Each scenario follows established Nginx best practices so you can paste it straight into your site configuration.
SSL, Gzip and www in one click
Ticking the SSL box adds Let's Encrypt certificate paths, TLS 1.2/1.3 protocols and a secure cipher suite, plus a 301 redirect from port 80 to HTTPS. The Gzip option enables compression for common text types. The www redirect produces a separate server block that points the www subdomain at your bare domain. The entire config is assembled in your browser, so no data is ever sent to a server.
Frequently asked questions
Does proxy mode support WebSockets?
Yes. The proxy block sets the Upgrade and Connection headers and uses proxy_http_version 1.1, so WebSocket connections are upgraded correctly.
What is the difference between static and SPA mode?
Static mode returns a 404 for missing files; SPA mode routes every unmatched request to index.html so that client-side routers work on page refresh.
Does this tool obtain the certificates for me?
No. It only writes the config that points to Let's Encrypt certificates. You still need to obtain them separately on your server with a client like certbot.

Yes. Nginx Config Generator and all 300+ tools on MagmaNex are completely free with no signup or account required.
