Nginx Config Validator

Checking Nginx Configuration Before Reloading Servers

Nginx configuration files often include server blocks, location rules, redirects, proxy settings, headers, SSL settings, and static file paths. A small missing brace, missing semicolon, or incorrect directive can stop Nginx from reloading correctly.

This Nginx Config Validator helps you check Nginx configuration snippets for common syntax issues, brace mismatches, missing semicolons, duplicate server names, proxy settings, and basic server block mistakes directly in your browser.

Reviewing Server Blocks, Locations, and Proxy Rules

1. Paste an Nginx configuration snippet into the input box.
2. Click Check Config.
3. Review warnings and suggestions in the validation report.
4. Run nginx -t on your server before applying changes.

Common Nginx Config Validator Use Cases

• Checking server blocks before adding them to production.
• Finding missing semicolons in Nginx directives.
• Reviewing reverse proxy settings such as proxy_pass.
• Checking brace balance in nested location blocks.
• Reviewing redirects, server names, and header directives.

Example Nginx Configuration

server {
  listen 80;
  server_name example.com www.example.com;

    proxy_pass http://localhost:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
  }

  location /static/ {
    root /var/www/example;
  }
}
