Nginx Reverse Proxy Config Auditor

Audit Nginx server, location, upstream and proxy_pass configuration in the browser, including TLS/SNI, WebSocket, timeout and URI replacement risks.

Configuration is analyzed statically in the browser
Nothing is uploaded, Nginx is not executed, include files are not read and upstreams are not contacted. Anonymous events contain no hosts, paths or content.

Nginx config and route example

One configuration up to 2 MiB. Includes, rewrites and variable runtime behavior are not executed.

Route simulation inputs

The parser provides a static approximation and does not replace nginx -t.

Paste a config to understand proxy behavior

The audit will show a configuration tree, findings, fix snippets and Host/Path route simulation.

This bounded static check is not nginx -t and does not cover dynamic modules, disk includes, DNS, the full rewrite lifecycle or all runtime inheritance. Validate in the target environment.
