scc (Sloc, Cloc and Code) counts lines of code across 322+ languages and goes further than cloc or tokei by estimating cyclomatic complexity per file and producing COCOMO development cost estimates. It is optimized for multi-core CPUs and benchmarks faster than tokei.

Features

  • Counts code, comment, and blank lines across 322+ languages
  • Approximates cyclomatic complexity via branch detection
  • COCOMO and LOCOMO (LLM-based) cost estimation
  • Duplicate file detection to measure DRYness
  • Detects and flags minified and auto-generated files
  • Multiple output formats: tabular, JSON, CSV, HTML, SQL, OpenMetrics
  • Respects .gitignore, .ignore, and custom .sccignore files
  • Can run as a Model Context Protocol server for LLM integration
