Code Line Counter is a free, browser-based counter that counts code line. Counts are updated in real time as you type or import content. Your inputs stay on your device at all times — nothing is uploaded or transmitted to any server. Used daily by front-end developers, back-end engineers, and full-stack teams. Code Line Counter works on phones, tablets, and desktops — wherever you are.

Count Every Line of Code in Your Project

Knowing the size of your codebase is more useful than you might think. Whether you are estimating project complexity, writing a proposal, tracking progress over a sprint, or simply satisfying your curiosity, the Code Line Counter gives you an accurate breakdown of your source code in seconds. Paste your code or upload files, and the tool counts total lines, code lines, comment lines, and blank lines separately.

More Than Just a Number

A raw line count tells you something, but a detailed breakdown tells you much more. The Code Line Counter distinguishes between lines that contain executable code, lines that are purely comments, and lines that are blank. This distinction matters because a file with 500 lines of code and 200 lines of comments is very different from a file with 700 lines of uncommented code. Understanding that ratio helps you assess documentation quality and maintainability at a glance.

How the Code Line Counter Works

Paste a block of code into the input field or upload one or more source files from your machine. The tool analyses each line and classifies it as code, comment, or blank based on the syntax patterns of the detected language. Single-line comments, multi-line comment blocks, and inline comments are all handled correctly. The results appear as a clear summary with counts and percentages for each category.

Language Support

The Code Line Counter recognises comment syntax for a wide range of programming languages including JavaScript, TypeScript, Python, Java, C, C++, C#, PHP, Ruby, Go, Rust, Swift, Kotlin, HTML, CSS, SQL, Shell scripts, and YAML. Each language has its own comment delimiters, and the tool applies the correct rules automatically. If the language cannot be detected, you can select it manually from a dropdown.

Use Cases That Go Beyond Curiosity

Software consultants use line counts in proposals and project estimates. Engineering managers track codebase growth over time to identify bloat or measure team output. Open source maintainers include line count badges in their README files. Students completing assignments use the Code Line Counter to verify they meet minimum requirements. Security auditors use it to gauge the attack surface of an application. Whatever your reason, having precise numbers beats guessing.

Batch File Analysis

If you have multiple files to analyse, you can upload them all at once. The tool provides per-file breakdowns as well as an aggregate summary across all files. This is especially handy when you want to understand the composition of a module or a microservice without cloning a repo and running a CLI tool like cloc or tokei. Just drag your files in and get instant results.

Comment-to-Code Ratio

One of the most insightful metrics the Code Line Counter provides is the comment-to-code ratio. A ratio below five percent may indicate under-documented code that will be hard for new developers to maintain. A ratio above fifty percent might suggest over-commenting or auto-generated documentation that adds noise without value. This single metric can spark productive conversations in code reviews and retrospectives about documentation practices.

Completely Private and Free

Your source code stays on your machine. The Code Line Counter runs entirely in the browser, so nothing you paste or upload is ever transmitted to a server. Use it freely on proprietary code, client projects, and confidential repositories without any data privacy concerns.
