In their own words
snpm
snpm is a free, open-source package manager for Node.js projects and JavaScript workspaces. It runs on Linux, macOS, and Windows, with native binaries for x64 and arm64. Its CLI provides npm-style install, add, run, exec, and dlx commands, plus auditing, dependency inspection, license listing, patching, packing, publishing, and store maintenance. Workspaces can be filtered by name, glob, path, dependency walk, or Git reference. snpm imports pnpm, Bun, Yarn, or npm lockfiles when snpm-lock.yaml is missing, then uses its own lockfile as the source of truth. Packages are downloaded once into a shared store and linked through a node_modules/.snpm virtual store. Lifecycle scripts are blocked unless allowed, package age can be restricted, and tarball authentication is registry-scoped. Publishing includes workspace fan-out, tags, OTP, and dry-run modes. An included Node manager handles version installation and discovery. The npm install script requires Node.js 18 or newer.
Yarn
Yarn is a package manager and project manager for JavaScript projects, serving uses from simple projects to industry monorepos. It resolves dependencies, maintains lockfiles and provides workspaces that install and link packages within a project. Modern Yarn uses Plug'n'Play by default, generating a Node.js loader file instead of a typical node_modules folder; users can choose node_modules or pnpm-style symlink installs instead. Yarn caches installed packages and shares them among projects on the same machine. Its offline mirror and zero-installs workflow can keep cached packages in a repository and reduce reliance on the npm registry. Plugins can extend resolvers, fetchers, linkers, commands and lifecycle hooks. Generated editor SDKs and settings support VSCode, Vim, Emacs and Neovim. Yarn runs on Linux, macOS and Windows and is free, with no paid plans or usage limits stated. Its documentation notes that React Native and Expo require typical node_modules installs. Yarn does not run audits during installation by default; users can run yarn npm audit separately.
