Fallow

What is Fallow?

Run npx fallow audit in any TypeScript or JavaScript repository. Fallow builds a deterministic dependency graph, then reports unused code, cycles, duplicated logic, complexity, and architecture drift. Its changed-code gate blocks only findings introduced by the current change, so existing debt does not stop adoption. Use the same evidence locally, in CI, editors, and MCP workflows. The analyzer is free and MIT licensed; optional Fallow Runtime adds production execution evidence.
