Static analysis engine providing quality scores, PR risk, hotspots, duplication, architecture, and cleanup intelligence for JavaScript/TypeScript codebases.
Is it any good?
Effectiveness · benchmark pending
We haven't benchmarked Fallow yet, so its score is provisional — computed from safety, maintenance, and documentation only, with popularity given no weight. When we benchmark it, we measure whether it produces materially better output than a frontier model alone, and that result leads the score. How we measure.
About Fallow
Description · AI-summarised from the fallow-rs README
Fallow is a Rust-native codebase intelligence engine that analyzes TypeScript and JavaScript repositories to produce deterministic findings: health scores, changed-code risk assessments, complexity hotspots, duplication detection, architecture violations, dependency hygiene, and cleanup opportunities. It provides structured JSON output, typed output contracts, MCP server integration, and LSP support—enabling both human reviewers and AI agents to make evidence-based decisions. No AI inside the analyzer; all findings are deterministic and traceable. Includes optional runtime intelligence layer (paid) that adds production execution evidence.
