A simple Python3 tool to detect similarities between files within a repository

Code pattern analysis for JS

Analyze key metrics like number of words, readability, complexity, code duplication, … of any kind of text

🚀 Cloc & duplicate code checker tool

Technical debt and risk analyzer that predicts bug hotspots by combining cognitive complexity, pattern recognition, coverage gaps, information theory, and git history.

Agent skills for the JavaScript/TypeScript codebase analyzer. Teaches AI agents how to find unused code, circular deps, duplication, complexity, and boundary violations with fallow. Works with Claude Code, Cursor, Codex, Gemini CLI, and 30+ agents.

Too little variation - A tool to discover code duplication in various languages

Language-agnostic Incremental Code Duplication Detection

Identify embedded C and C++ libraries

Anti-slop Python code duplication finder. Detects structurally identical functions across your codebase, rename-invariant. Local first, WASM based.

Main entrypoint of quality of JS packages project.

Analyzing the evolution of a software system

Code Similarity detection for Python files and Jupyter Notebooks

CloneHunter finds duplicate code across mixed-language repositories. It runs a semantic retrieval pipeline with model inference and indexing to catch harder, non-trivial duplicate patterns.
