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; Docusaurus customisation past the config file assumes React knowledge, which not every docs team has
- They diverge on capability: Rollup covers Tree shaking, Docusaurus covers MDX authoring.

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
Docusaurus
- Customisation past the config file assumes React knowledge, which not every docs team has
- Build times grow noticeably on very large sites, particularly with many versions and locales
- Major version upgrades have required real migration work rather than a dependency bump
- It generates a static site, so anything dynamic — gated content, per-user docs — needs a separate solution

Answered from the vendors’ own pages
Rollup: Is Rollup free?
Yes, open source under the MIT licence.
Docusaurus: Is Docusaurus free?
Yes. Docusaurus is open source from Meta with no licence fee. You pay only for hosting, and static output can be served from free tiers on Netlify, Vercel or GitHub Pages.
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.
Docusaurus: What is Docusaurus built with?
React and MDX. Pages are authored in MDX — Markdown that can embed React components — and the theme layer is React, so layouts are extended with components.
Rollup: Do I need Rollup if I use Vite?
Not directly. Vite uses Rollup for production builds, so you already benefit from it.
Docusaurus: Does Docusaurus support multiple documentation versions?
Yes. Versioning is built in, so documentation for several released product versions can be maintained side by side, which is a main reason projects choose it.
Docusaurus: Does Docusaurus include search?
It integrates with Algolia DocSearch rather than shipping its own search index. Open-source projects can typically use Algolia’s free DocSearch programme.
