Rush vs snpm

Rush is a monorepo manager for JavaScript developers who build and publish many packages from a shared Git repository. It can install dependencies, link projects, build, generate change logs, update versions, and publish packages to an npm registry. Build modes include parallel, subset, incremental, and distributed builds. Rush puts dependencies in a common folder and uses symlinks to recreate a node_modules folder for each project. Its installation algorithm supports PNPM, NPM, and Yarn. For releases, it gathers change files and updates package versions and changelogs before publishing. Project folders remain self-contained: they can be built without Rush or moved to a separate repository without code changes. Rush runs on Linux, macOS, and Windows; its getting-started demo lists NodeJS as the only prerequisite. Plugins can share configuration and extend features, but the plugin framework is marked experimental. Microsoft does not provide official support; community help is directed to GitHub issues and Rush Stack Zulip. Rush is free and open source.

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.
