cnpm vs Utoo

cnpm is an npm client for the China mirror of npm. It supports npm commands for package installation and synchronization, and can open package documentation or a Git web URL. Global installation uses `npm install cnpm -g`, and the minimum Node.js version is 20, with LTS recommended. Users can configure a custom registry, registry web address, and user configuration file to create a private-registry npm CLI. cnpm uses npminstall by default, though the original npm installer can be selected at the stated cost of losing the fastest install speed. The mirror is read-only and aims to synchronize with the official service in real time, so write-related operations are excluded. npminstall accepts folders, tarballs, URLs, registry packages, and Git URLs. Its options include ignoring lifecycle scripts, omitting optional dependencies, enforcing registry-only installs, and forbidding specified licenses. It cannot install from shrinkwrap files, and failed installs are best retried after cleaning `node_modules`. The project is MIT licensed and recommends migrating to utoo, described as a modern npm package manager. cnpm runs on Linux, macOS, Windows, and self-hosted environments.

Utoo is a unified web development toolchain for package management, bundling, and browser-native builds. Its Rust-based package manager works with npm packages and registries, reads and writes standard package-lock.json v3 files, and reuses cached packages across projects through hard links. It supports isolated workspaces for monorepos and documents a one-command migration from pnpm that converts workspace, override, and catalog settings. The @utoo/pack bundler uses Turbopack and SWC, with incremental builds and persistent caching. Listed bundler capabilities include HMR, code splitting, Lightning CSS, Webpack loader compatibility, bundle analysis, and image optimization. For browser-based development, @utoo/web uses WebAssembly and OPFS for package installation, builds, and HMR; its playground runs without a server. Utoo supports Linux, macOS, Windows, and web, and is open source under the MIT License. With cnpm-compatible registries such as npmmirror, it can use server-side semver resolution and redirect native-module downloads to a binary mirror CDN; both optimizations are off on the official npm registry.
