shadcn/ui

  • No upgrade path: once copied, upstream fixes and improvements are yours to port by hand
  • Requires Tailwind and React, so it is not an option outside that stack
  • Component code lives in your repository, which grows it and puts maintenance on your team
  • Its popularity has made the default look recognisable, which undercuts the customisation argument

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.

Source
shadcn/ui: Is shadcn/ui free?

Yes, open source and free for commercial use.

pnpm: 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.

Source
shadcn/ui: Why is it not an npm package?

So you own the code. Components are copied into your project, which makes customisation trivial — at the cost of receiving no automatic updates.

pnpm: 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.

Source
shadcn/ui: Do I need Tailwind?

Yes. Components are styled with Tailwind utility classes and built on Radix primitives, so both are required.

pnpm: 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.

Source
pnpm: 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.
