Fallow gives Codex fast, local-first codebase analysis for TypeScript and JavaScript. Audit changed-code risk, find dead code and unused dependencies, detect duplication and complexity hotspots, inspect architecture boundaries, and prioritize safe cleanup. Fallow Impact explains the latest full-project issue count, its comparable trend, and findings cleared while tracking. Optional cloud and product telemetry workflows run only after explicit user action.
