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

Fallow is a Rust-based static analyzer for JS/TS codebases that detects unused files, exports, dependencies, circular dependencies, and duplicated code in sub-second time. It leverages the Oxc parser natively in Rust with rayon for parallel processing, significantly outperforming existing tools like knip. With zero configuration and 84 auto-detected framework plugins, it addresses the growing problem of dead code accumulation, especially in AI-assisted development workflows.
