Fallow analyzes your codebase at two levels:
  • Static intelligence: structure, reachability, duplication, complexity, boundaries, and flags
  • Runtime intelligence: what actually executed in production

​
Static analysis

Dead code

Unused files, exports, types, dependencies, circular deps, and more.

Duplication

Find repeated blocks from exact to semantic clones.

Architecture boundaries

Enforce import rules across layers and modules.

Auto-fix

Remove unused exports and dependencies automatically.

​
Runtime analysis

Runtime coverage

Add runtime evidence to fallow health for hot paths, cold paths, and deletion confidence.

​
Supporting topics

Production mode

Exclude test and dev files from analysis.

Non-JS file types

How Fallow handles JSON, HTML, and other file types.

CSS, SCSS, and Tailwind

AST-based CSS Module, SCSS, and Tailwind tracking.

Debugging

Trace why something is reported (or missed).

Limitations

What Fallow does not cover and why.
