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.

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.

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

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

Find structurally similar Ruby methods with normalized Ripper fingerprints

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

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.

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

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