Fallow: codebase intelligence for JavaScript and TypeScript

Codebase intelligence for JavaScript and TypeScript. The free static layer reports quality, changed-code risk, cleanup opportunities, circular dependencies, code duplication, complexity hotspots, architecture boundary violations, feature flag patterns, and opt-in security candidates. Runtime coverage merges production execution data into the same fallow health report for hot-path review, cold-path deletion confidence, and stale-flag evidence, with a single local capture available by default and continuous/cloud runtime monitoring available as an optional mode. 122 framework plugins, zero configuration, sub-second static analysis.
