Source lines of code (SLOC) counters are essential utilities used by developers to analyze codebases, estimate project sizes, and determine the ratio of actual code to comments and blank lines. Choosing the right tool depends heavily on your requirements for processing speed, programming language support, and integration capabilities.
The top 5 free and open-source source line counter tools are reviewed below based on their performance, features, and usability.

The most widely known and recognized tool in the open-source community is the official cloc GitHub Repository. It has been a developer staple for nearly two decades due to its reliability and exhaustive feature list.
Language Support: Recognizes hundreds of programming and configuration languages out of the box.
Features: Completely filters out comment lines and blank lines, tracks differences between two separate directory versions, and processes compressed archives (.zip, .tar.gz) seamlessly.
Downside: Written in Perl, it can operate noticeably slower on massive codebases compared to modern compiled alternatives. GitHub – boyter/scc: Sloc, Cloc and Code
