Nginx Config Builder

Build Nginx server block configurations with templates and helpful hints.

Server Configuration

Server Type

Forwards incoming requests to a backend application server. Useful when your app runs on a different port (e.g., Node.js on 3000, Python on 8000). Nginx handles SSL termination and forwards requests with proper headers.

Server Name

Domain name or IP address. Use _ for catch-all or default server.

Listen Port

Port to listen on. Common: 80 (HTTP), 443 (HTTPS).

Proxy Pass URL

Backend server URL (e.g., http://localhost:3000 or http://127.0.0.1:8080).

How it works: Nginx receives requests and forwards them to your backend server. The generated config includes proper proxy headers (Host, X-Real-IP, X-Forwarded-For) so your application can identify the original client. This is essential for apps behind a reverse proxy.

Client Max Body Size

Maximum request body size (e.g., 10m, 100m).

Limits upload size. Common: 10m, 50m, 100m. Leave empty for default (1m).

Rate Limit Zone

Rate limit zone name and rate (e.g., api_limit 10r/s).

Requires a rate limit zone defined in http context. Example:limit_req_zone $binary_remote_addr zone=api_limit:10m rate=10r/s;

Enable SSL/TLS

Custom Directives (optional)

Generated Nginx Config

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

}
