Fallow: Codebase Analyzer

The codebase analyzer for JavaScript and TypeScript. Finds unused code, circular dependencies, code duplication, and complexity hotspots. 84 framework plugins, zero configuration, sub-second performance. 3-36x faster than knip, 20-33x faster than jscpd.

When to Use

Finding dead code (unused files, exports, types, enum/class members)
Finding unused or unlisted dependencies
Detecting code duplication and clones
Cleaning up a codebase before a release or refactor
Auditing a project for codebase hygiene
Setting up CI checks for dead code or duplication thresholds
Migrating from knip or jscpd to fallow
Investigating why a specific export or file appears unused

When NOT to Use

fallow
Codebase intelligence for JavaScript and TypeScript. Free static layer finds unused code (files, exports, types, dependencies), code duplication, circular dependencies, complexity hotspots, architecture boundary violations, and feature flag patterns. Runtime coverage merges production execution data into the same health report for hot-path review, cold-path deletion confidence, and stale-flag evidence - a single local capture is free, while continuous/cloud runtime monitoring is paid. 94 framework plugins, zero configuration, sub-second static analysis. Use when asked to analyze code health, find unused code, detect duplicates, check circular dependencies, audit complexity, check architecture boundaries, detect feature flags, clean up the codebase, auto-fix issues, merge runtime coverage, or run fallow.
