Fallow: Codebase Intelligence for TypeScript & JavaScript

Fallow is a codebase intelligence tool designed for TypeScript and JavaScript that provides both static and optional runtime analysis. The free static analysis layer identifies unused code, duplication, complexity hotspots, and architecture boundaries. The runtime layer offers insights into code execution based on real production traffic.

Key features:

• Static Analysis - Detects dead code, unused exports, and circular dependencies.
• Runtime Intelligence - Analyzes actual execution paths to inform code decisions.
• Zero Configuration - Runs without the need for setup, making it easy to integrate into existing workflows.
• Fast Performance - Provides results in sub-second times, enhancing developer efficiency.
• Extensive Plugin Support - Compatible with 90 different frameworks.

Fallow is particularly useful for teams employing AI-assisted development, as it helps ensure that generated code does not introduce issues such as dead code or increased complexity.
