duplicate-code

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.

phpcpd-next is a token-based copy/paste (clone) detector for PHP 8.5+, a modernized, openly-licensed successor to Sebastian Bergmann's phpcpd

Find dead cross-boundary methods (Workers DurableObject / RpcTarget / Agent) and structural clones in TypeScript. The linter layer that sits above knip/oxlint.

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

PMD CPD-compatible copy-paste detector that finds duplicate code in TypeScript, JavaScript, JSX/TSX, Vue, Svelte and Angular.

PyChase - Python duplicate code detector using AST normalization + MinHash LSH. Catches Type-1/2/3 clones in functions, methods, and classes with zero dependencies.

TypeScript-only similarity analyzer.

Measure your codebase from the terminal — lines per language, duplicate code, complexity ranking, token cost for AI agents, comment drift, and a refactor verdict per file. Zero config, one dependency, 100% test coverage.

Fully local clone detection for Rust, C and C++ — Type-1/2/3, build-free, with content-addressed finding IDs and SARIF output

Code similarity search by compression - find near-duplicate files, clone families, and where a pasted snippet came from. No embeddings, no model, no vector database.

Explainable, local structural similarity for Go, JavaScript, TypeScript, Python, and Rust.

Statischer Python-Code-Analyser mit Tkinter-GUI: findet ungenutzte Imports, tote Definitionen und ähnliche Code-Blöcke via AST-Analyse. Kein pip install nötig.

Agent skills for cleaning up codebase drift — stale comments, duplicate code, and inconsistent imports. Two-phase inventory-then-execute workflow for Claude Code, Cursor, and other AI coding agents.

Find structurally similar Ruby methods with normalized Ripper fingerprints

Safe dead-code analysis and cleanup skill for OpenCode with scoped approval, non-destructive backups, duplicate detection, and test verification.

Skill de faxina de codebase para Claude Code: remove código morto, detecta arquivos e funções duplicadas, consolida módulos rasos e reorganiza pastas, com commits atômicos e gate de testes com rollback provado

Dead code forensics for TypeScript — confidence tiers, evidence chains, and removal that refuses to guess.
