npm vs vcpkg

npm is a JavaScript package registry and command-line tool for sharing code and managing packages. The Registry and CLI are free for public package use, and the Free plan lets public package authors publish unlimited public packages. npm accepts package.json folders, gzipped tarballs, URLs, name-and-version or name-and-tag references, and Git URLs. Its tools support dependency resolution, lockfiles, workspaces, private registry authentication, and offline installation. It runs on Linux, macOS, Windows, and other operating systems through Node.js installers or version managers. For private packages, the Paid user account plan is $7 a month; Pro is also $7 a month for individual creators, while Teams is $7 per user per month for teams and organizations. Pro includes unlimited private packages and package-based permissions; Teams adds team-based permissions. Organizations can manage members, teams, roles, permissions, and package access. All plans include basic support and automatic security warnings. Paid billing starts when card details are submitted, with the first month charged immediately.

vcpkg is a free package manager for acquiring and managing C/C++ libraries. Its curated registry contains over 2,300 open-source libraries, with dependency resolution across Windows, macOS, Linux, Android, and iOS. Projects can declare dependencies, optional features, and version constraints in manifest files; baseline version sets and individual package pins help keep dependency choices reproducible. vcpkg integrates with CMake and MSBuild, while manual integration is supported for other build systems. Built packages can be cached for reuse across developer machines and continuous integration runs. Asset caching can mirror source assets and build tools for offline or air-gapped environments. Users can also create custom registries for private libraries, patches, or other packages. Documented editor integrations include Visual Studio, Visual Studio Code, CLion, and Qt Creator. The project says most ports use libraries' original build systems and obtain source code and tools from their official distribution locations. vcpkg collects anonymous usage data, with opt-out options. Firewall access needs depend on the ports installed.
