Top Open-Source LOC Counter GUI Apps to Try Today Lines of Code (LOC) is a foundational metric for software development. It helps estimate project size, track progress, and evaluate codebase complexity. While command-line tools like Cloc are powerful, graphical user interface (GUI) applications offer an intuitive, visual approach to analyzing codebases without memorizing terminal commands.
Here are the top open-source LOC counter GUI applications you can use to visualize and audit your repositories today. 1. Count Lines of Code (CLOC) GUI
Many developers prefer the reliability of the original cloc command-line tool but want a visual interface. Several community-driven open-source wrappers provide a clean GUI layer directly over the standard Cloc engine.
Key Benefit: Combines the industry-standard accuracy of Cloc with simple button clicks.
Best Feature: Easily filter out third-party vendor folders (node_modules, pods) via an interactive checklist.
Export Options: Instantly saves reports into structured CSV, JSON, or TXT formats.
Gcloc is a lightweight, modern open-source LOC counter built with Go and a fast GUI framework. It focuses entirely on execution speed and cross-platform performance.
Key Benefit: Extremely fast scanning speeds, even on massive monorepos with hundreds of thousands of files.
Best Feature: Live progress bars and immediate visual rendering of code statistics upon directory selection.
Platform Support: Offers native, lightweight binaries for Windows, macOS, and Linux without heavy dependencies. 3. Ohcount GUI
Based on the powerful Ohcount analysis engine (originally created for the Open Hub platform), this GUI app goes beyond simple line counting to provide deeper architectural insights.
Key Benefit: Superior accuracy in detecting multi-language files, such as HTML files containing embedded JavaScript and CSS.
Best Feature: Explicitly separates actual code logic from syntax comments and empty blank lines.
Visual Representation: Displays a clean, proportioned breakdown of language distribution across the entire project. 4. LocMetrics (Open-Source Alternatives)
While the original LocMetrics was a popular proprietary utility for Windows, modern open-source recreations have modernized its classic, straightforward layout.
Key Benefit: Simple, single-window layout optimized for quick, no-fuss local directory auditing.
Best Feature: Displays direct, side-by-side comparisons of physical lines versus logical lines of code.
Ideal For: Legacy C#, C++, and Java developers who need a quick compliance or estimation metric.

If you want to run a quick test on your project, let me know:
What programming languages make up the bulk of your codebase? What operating system (Windows, macOS, Linux) do you use? Do you need to export the data into charts or spreadsheets? I can recommend the absolute best fit for your workflow.
