How to Use Nginx Config Generator

  1. 1

    Select server type

    Choose your use case: reverse proxy, static file server, load balancer, SSL terminator, or API gateway.

  2. 2

    Configure upstream servers

    Add backend servers with IP:port. The generator creates upstream blocks and optionally adds load balancing algorithms (round-robin, least-conn).

  3. 3

    Enable SSL/TLS

    Paste your certificate and key paths. The generator creates full SSL configuration with strong ciphers, HSTS headers, and redirect from HTTP.

  4. 4

    Add routing rules

    Define location blocks with URL patterns, proxy passes, and header rewrites. Support for regex, exact matches, and priority ordering.

  5. 5

    Copy config and deploy

    Export the complete nginx.conf or individual server blocks. Copy to /etc/nginx/sites-enabled/ and run 'nginx -t' to validate before reload.

Frequently Asked Questions

What nginx configurations can this generate?
Static sites, reverse proxies, load balancers, SPA hosting (React/Vue), and API gateways — all with optional SSL/TLS, security headers, caching, gzip compression, and rate limiting.
Does it include SSL configuration?
Yes, with Mozilla Intermediate profile cipher suites, TLSv1.2/1.3 support, HSTS headers, and a generated Let's Encrypt certbot command for easy certificate setup.
Can I add security headers?
Yes, toggle OWASP-recommended headers including X-Frame-Options, Content-Security-Policy, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy.
Does it validate the generated config?
The tool generates syntactically correct nginx configs with inline comments. For full validation, run 'nginx -t' on your server after deploying the configuration.
Is this tool free?
Free to use. Your server configuration is generated entirely in your browser and not sent to external services.
