ToolbitNginx Configuration Validator and Formatter
Check an nginx config for the structural mistakes that make a reload fail — unbalanced braces, missing semicolons, malformed directives — before you touch the server.
What the Nginx Config Validator does
- Brace balance and missing-semicolon detection with line numbers.
- Consistent reindentation of nested blocks.
- Directive summary for server, location, and upstream blocks.
- Flags common misconfigurations in proxy_pass and try_files.
How to use it
- Paste your nginx.conf or site config.
- Review the reported issues and directive summary.
- Copy the formatted config back to the server.
Why it runs locally
Toolbit has no backend. The Nginx Config Validator is implemented with standard browser APIs, so your input is processed in the tab and never uploaded, logged, or retained. That is what makes it safe to paste real data into — and it is also why the tool keeps working with the network disconnected, once you have installed Toolbit as an app.
Frequently asked questions
- Does this replace nginx -t?
- No. It catches structural and syntax problems early, but only nginx -t on the real server knows about your modules, paths, and certificates.
- Can I paste a config containing secrets?
- No. Every Toolbit tool runs entirely in your browser using standard Web APIs. Your input is never uploaded, logged, or sent to a third party — you can open the network tab and watch it stay quiet.
- Does it understand included files?
- It analyses the file you paste. Includes are listed but their contents are not fetched.
