Flux vs snpm

Flux is an open-source command-line package manager for JavaScript and Node.js projects, built by Gautam Suthar. It installs, updates, lists, and removes packages from the npm registry, and runs scripts defined in package.json. Packages are placed in node_modules, while downloaded tarballs remain in a shared per-user cache that later projects can reuse. Flux is available through a global npm installation or as a standalone binary without Node.js. The npm route requires Node 18 or later; the standalone binary includes no runtime. It runs on Linux, macOS, and Windows, uses package.json, and has no workspace or lockfile support. The alpha handles direct dependencies only, without dependency-tree resolution, so installs are not reproducible. Flux has no telemetry, requires no account, and is MIT licensed for personal and commercial use. The maker recommends it for side projects and experiments, not production projects.

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.
