## What it is
Utoo is a unified, high-performance web development toolchain written in Rust, combining an npm-compatible package manager (utoo/ut), a Turbopack-powered bundler (@utoo/pack), and a WASM-based browser version (@utoo/web). It aims to replace npm/pnpm and webpack/turbopack setups with a single fast, cohesive tool.

## Use cases
- install npm dependencies faster than pnpm or bun
- replace npm with a rust package manager that reads package-lock.
- bundle a typescript react app with hot module replacement
- manage a monorepo with workspaces and catalogs
- migrate a pnpm project with one command
- run package scripts and remote CLIs like npx
- bundle javascript in the browser via wasm

## When to choose
- you want a fast drop-in npm replacement with native lockfile compatibility
- you need package management, bundling, and dev server in one unified toolchain
- you maintain monorepos and want optimized workspace installs and global caching
- you want webpack-compatible bundling with turbopack/swc performance

## When to avoid
- your project depends on deep npm/pnpm ecosystem tooling or plugins not yet supported
- you need a battle-tested, long-proven package manager for critical production pipelines
- you rely on yarn-specific features or non-standard lockfiles
