srcmetricsLanguage-independent source code metrics

Size, complexity, nesting, Halstead, duplication, dependencies and documentation — one definition for C, C++, Go, Java, JavaScript, Python, Rust and TypeScript.

One definition, every language

Code is parsed with tree-sitter into a small common representation, and every metric is computed from it. The same algorithm in eight languages gets the same cyclomatic and cognitive complexity.

Raw features, not a score

53 metrics at function, file and project scope, reported separately for statistical analysis. There is no built-in "readability score".

Honest values

A value that does not apply is null with its reason, never 0. Files that fail to parse are reported, never dropped.

Reproducible

Every result records the commit, parser versions and metric definition version it was computed with.

CLI, library and HTTP API

Export JSON or CSV, get statistics and self-contained HTML reports, or embed the Rust library.

Bring your own labels

If you have human readability ratings, fit an experimental ridge-regression model on them.
