Code Line Counter — Free, No Upload, Browser-Based

Code Line Counter breaks down any pasted source file into total, code, comment, inline-comment, and blank lines — instantly, as you type. It auto-detects 17 common languages (JavaScript, TypeScript, Python, Go, Rust, SQL, HTML, CSS, and more) or you can pin the language yourself. Everything runs in your browser: your code never leaves your machine and no file is uploaded anywhere.

Så här använder du det här verktyget

1. Open the tool, optionally select your language (or leave it on Auto-detect), and paste your code into the text area.
2. Results appear instantly — total lines, pure code lines, comment lines, inline-comment lines, and blank lines, each with a percentage share.
3. Click Copy next to any count to copy the number to your clipboard, or read the visual bar breakdown to compare the composition at a glance.
