Fast tools for slow problems. I build Rust-native developer tooling for the JavaScript ecosystem.
Codebase analyzer for JS/TS. Finds unused code, circular dependencies, code duplication, complexity hotspots, and architecture boundary violations. 3-40x faster than knip, 16-33x faster than jscpd.
npx fallow # all analyses — zero config, sub-second
npx fallow dead-code # unused files, exports, deps
npx fallow dupes # clone detection
npx fallow health # complexity + maintainability
npx fallow boundaries # architecture boundary enforcement90 framework plugins, VS Code extension, LSP, MCP server, GitHub Action, GitLab CI template. Docs | Repository
