About the Nginx Config Analyzer

Paste an Nginx configuration to check brace balance and missing semicolons, then review server and location blocks for missing server_name, plain HTTP without a redirect, outdated SSL protocols, missing security headers, wide-open CORS, unsafe proxy_pass headers, autoindex and server_tokens exposure, and gzip or caching opportunities.

Examples

Missing header

server { listen 443 ssl; }

Output

YAMLWarning: no Strict-Transport-Security header
