Answered from the vendors’ own pages
pnpm: Is pnpm free and open source?
Yes. pnpm is free and open source software developed for Node.js. Version 10 and 11 are currently available.
Sourcepnpm: How does pnpm save disk space?
pnpm uses a content-addressable store with hard linking and symlinks to avoid duplication. All files are saved in a single place on disk and hard-linked to individual projects, dramatically reducing storage requirements compared to npm.
Sourcepnpm: Is pnpm faster than npm?
Yes. pnpm performs installation in three stages: dependency resolution, directory structure calculation, and linking. Packages are fetched and linked as soon as possible, making it significantly faster than npm's sequential approach.
Sourcepnpm: Does pnpm support monorepos?
Yes. pnpm has built-in support for monorepositories. You can create a workspace using pnpm-workspace.yaml to unite multiple projects in a single repository.
Sourcepnpm: How does pnpm handle node_modules differently than npm?
pnpm uses symlinks to add only direct dependencies to node_modules root, preventing accidental access to undeclared dependencies. This encourages more explicit dependency management compared to npm's flattened node_modules structure.
