## When it is useful

Auditing a TypeScript or JavaScript codebase for unused code and dependencies, duplication, circular dependencies, complexity hotspots and boundary violations.

## The Catch

The Fallow CLI covers TypeScript and JavaScript only. The scan is MIT and free locally and in CI; production call counts need Fallow Cloud, which is $20 per seat per month after a 30-day trial.
