I built a Rust-based codebase analyzer that finds dead code in JS/TS projects in milliseconds

TL;DR: fallow is a Rust-native static analyzer for JS/TS codebases. It finds unused files, unused exports, unused dependencies, circular dependencies, and duplicated code. Zero config, 84 framework plugins auto-detected, sub-second on most projects. npx fallow check to try it now. The problem that kept bugging me Every codebase I've worked on has dead code. Exports that nothing imports. Dependencies in package.json that no file uses. Files that were "temporarily" left in after a refactor six months ago. Entire utility modules where 3 out of 12 functions are actually called. That dead code isn't free. It bloats your bundle, slows your builds, and confuses anyone new to the project because they can't tell what's actually used and what's left over from two refactors ago. And the longer nobody touches it, the scarier it gets to delete. This was annoying but manageable when humans wrote all the code. Now AI coding agents generate code at a pace where nobody can keep track of what's still ne
