Codebase intelligence for TypeScript and JavaScript. Free static layer: unused code, duplication, circular deps, complexity hotspots, architecture boundaries. Optional paid runtime layer: hot-path review and cold-path deletion evidence from real production traffic. Rust-native, sub-second, 90 framework plugins.

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

Code pattern analysis for JS

Code duplication detector for Elixir, powered by native AST analysis

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 fallow, codebase intelligence for JavaScript and TypeScript. Teaches AI agents how to find unused code, duplication, circular deps, complexity hotspots, architecture drift, and (with Fallow Runtime) hot-path and cold-path evidence. 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

Main entrypoint of quality of JS packages project.

Analyzing the evolution of a software system

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

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.

.NET code quality & duplication analyzer. Fast, extensible & Roslyn-based

An Arduino library which allows grouping of macros for your unique collection of development boards. Another advantage of this library is that it gives us development flexibility when working in parallel with various boards.

Code duplication detector with machine-readable output for AI agents - finds similar code blocks across C/C++/Python/Go/Java/JS for automated refactoring
