Code Line Counter

Analyze multiple source files directly in your browser and separate total lines into code, comments, and blank lines. Automatic extension-based language detection and per-file results help you understand a project without uploading its source code.

How to use the Code Line Counter

1Select one or more supported source files from your project.
2Review the detected language for each file.
3Adjust filters when generated files or specific patterns should be excluded.
4Compare total, code, comment, and blank line counts by file and language.
5Export the analysis as JSON when you need to save or compare the results.

Common uses

Estimate the composition of a small project or selected source directory.
Compare code and documentation levels across languages.
Exclude generated files before reporting project statistics.
Save a lightweight code-size snapshot for later comparison.

How lines are classified

The tool detects languages from file extensions and applies language-specific comment markers. Empty lines are counted separately from comment and code lines.

Line counts are useful project measurements, but they do not measure complexity, quality, productivity, or maintainability by themselves.

Local source file analysis

Selected files are read with browser file APIs and analyzed locally. Your source code is not uploaded to the WebUtils server.

Frequently asked questions

Does the counter upload my source code?

No. Selected files are read and analyzed locally in your browser.

How is the programming language detected?

The tool maps each filename extension to a supported language and then applies the matching comment syntax.

Are lines of code a measure of code quality?

No. Line counts describe project size and composition, but they should not be used alone to judge quality or developer productivity.
