Nginx Config Validator

Nginx Config Validator

This client-side validator checks nginx configuration files for common syntax problems without needing to run nginx -t on a server. It detects unbalanced braces (a common cause of nginx refusing to start), directives that appear to be missing a trailing semicolon, empty blocks, duplicate root directives within a block, proxy_pass lines without semicolons, and common typos like server_names or locaton. For production use, always run the official nginx -t command on your server as the final validation step. All processing happens in your browser — no configuration data is uploaded.
