The short version

  • Each has a real cost: React jSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript; Rollup slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
  • They diverge on capability: React covers Component-based architecture, Rollup covers Tree shaking.

  • Builds where output size and cleanliness matter more than build speednot React
  • Producing ES module output for consumers who will bundle it themselvesnot React

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

React

  • JSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript
  • Routing and state management are separate dependencies, not included in core library
  • Configuration complexity for advanced features like server-side rendering without a meta-framework
  • Requires choosing and configuring build tools and development environment setup

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

Answered from the vendors’ own pages

React: Is React free to use commercially?

Yes. React is distributed under the MIT open-source license, which permits free usage for both personal and commercial projects without licensing fees or restrictions.

Source
Rollup: Is Rollup free?

Yes, open source under the MIT licence.

React: Does React support TypeScript?

Yes. React works seamlessly with TypeScript for type-safe component development. TypeScript provides static type checking for React components, props, and state, improving code reliability and developer experience.

Source
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.

React: Do I need a build step to use React?

If you use JSX, yes. JSX requires transpilation by a build tool like Webpack and Babel before browsers can execute it. However, React can be used without JSX by calling React.createElement directly, which does not require a build step.

Source
Rollup: Do I need Rollup if I use Vite?

Not directly. Vite uses Rollup for production builds, so you already benefit from it.

React: Can I build offline-capable applications with React?

Yes. React supports building Progressive Web Apps (PWAs) with service workers and IndexedDB for offline functionality. Create React App includes service worker setup, though it must be manually enabled for production use.
