Count total, code, comment and blank lines (SLOC) plus functions for pasted code. Free and private: runs in your browser.
Paste code to see source lines of code, comment-only lines, blank lines, function count and comment ratio.
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.

Frequently asked questions
What is SLOC?
Source lines of code: lines that contain code, excluding blank lines and comment-only lines. It is the usual base for size and debt-ratio metrics.
Is the Lines of Code Counter 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.
