I Built this after getting burned one too many times by generators that "look right" but throw obscure errors the moment you actually deploy them. So this one doesn't! Every config option was run through the real Nginx and Apache binaries to confirm it actually works. Did you know ProxyPass isn't legal inside .htaccess at all, even with AllowOverride All? Neither I! No signup, nothing stored. It all runs in your browser. Would love feedback, especially if you hit a config combo that trips it up.
