About this code line counter

This free code line counter measures how big a project really is. Select or drag a folder and it reports total lines of code, comment lines, blank lines and file counts, broken down by programming language.

Everything runs inside your browser, so your source code is not uploaded anywhere. It is handy for estimating project size, writing a proposal, reporting progress or comparing codebases.

Features

  • Lines of code, comments and blank lines counted separately
  • Per-language breakdown so you see which languages dominate
  • Drag and drop a whole folder instead of selecting files one by one
  • Private by design: processing happens locally in your browser

How to use the code line counter

  1. Open the tool and select a project folder, or drag it onto the drop zone.
  2. Wait a moment while the files are scanned.
  3. Read the totals and the language breakdown, and open any file to inspect its code.
