The short version
- Each has a real cost: Rollup slower than the Go and Rust bundlers that followed it, since it is written in JavaScript; shadcn/ui no upgrade path: once copied, upstream fixes and improvements are yours to port by hand
- They diverge on capability: Rollup covers Tree shaking, shadcn/ui covers Copy, not install.
Where they differ
Only the attributes on which Rollup and shadcn/ui actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), user rating (Not yet rated), category (Web Development).

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Rollup
- Slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
- Application concerns like dev servers and hot reloading are not its job, so app builds need Vite on top
- Configuration for non-trivial applications gets verbose compared with tools that assume more
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
Rollup: Is Rollup free?
Yes, open source under the MIT licence.
shadcn/ui: Is shadcn/ui free?
Yes, open source and free for commercial use.
Rollup: Rollup or webpack?
Rollup is the usual choice for libraries thanks to cleaner output and better tree shaking. webpack remains stronger for complex applications with heavy asset handling.
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.
Rollup: Do I need Rollup if I use Vite?
Not directly. Vite uses Rollup for production builds, so you already benefit from it.
shadcn/ui: Do I need Tailwind?
Yes. Components are styled with Tailwind utility classes and built on Radix primitives, so both are required.
