Codebase intelligence for TypeScript and JavaScript. Free static analysis of code and styles: unused code, duplication, circular deps, complexity hotspots, architecture boundaries, design-system drift. Optional paid runtime layer (Fallow Runtime): hot-path review and cold-path deletion evidence from real production traffic.

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

Code pattern analysis for JS

Code duplication detector powered by Elixir AST analysis

Agent skills for fallow, codebase intelligence for TypeScript and JavaScript. Teaches AI agents how to find unused code, duplication, circular deps, complexity hotspots, architecture drift, design-system drift, and (with Fallow Runtime) hot-path and cold-path evidence. Works with Claude Code, Cursor, Codex, Gemini CLI, and 30+ agents.

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

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

🚀 Cloc & duplicate code checker tool

Deterministic Structural Change Controller for AI-assisted Python development

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

Language-agnostic Incremental Code Duplication Detection

Fast native Rust clone of jscpd for duplicate-code detection in CI/CD

A tool for find code duplicated functions in codebases

Executable codebase standards for Python: quality, style, architecture, and structure, checked mechanically on every commit. Ready-made checks (normes) cover the common ground; a plugin interface lets a team add its own. The same gate runs in CI and inside an AI agent's loop. Docs: https://lanorme.github.io/lanorme/

Identify embedded C and C++ libraries

v1 — superseded by nonna v2: github.com/thebabush/nonna. Anti-slop Python code duplication finder; structural, rename-invariant, local-first WASM demo.

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

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.
