Naming Convention Checker
Check function, class and variable names against each language's conventions. Free and private: runs in your browser.
Paste code to find names that break the usual style: snake_case in Python, camelCase in Java and JavaScript, PascalCase methods in C#, and cryptic one-letter names.
Runs entirely in your browser. Nothing you paste is uploaded or stored.
Use cases
- Check a function before opening a pull request.
- Explain a review comment with numbers instead of opinions.
- Find the riskiest code to refactor first.
Frequently asked questions
Do naming conventions really matter?
Consistent names make code predictable to read and search. They also prevent bugs in languages where case changes meaning, such as exported names in Go.
Is the Naming Convention Checker free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
How accurate is a browser-based code check?
It uses fast heuristics on the snippet you paste, so it is great for quick feedback. For whole repositories, cross-file analysis and history, run a full CodeInspector scan.
