The short version

  • Each has a real cost: Docusaurus customisation past the config file assumes React knowledge, which not every docs team has; Eclipse high memory consumption and CPU usage, especially with multiple plugins installed
  • They diverge on capability: Docusaurus covers MDX authoring, Eclipse covers Java development environment.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

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

Eclipse

  • High memory consumption and CPU usage, especially with multiple plugins installed
  • Slow startup times and performance degradation with large projects or many open editors
  • Requires configuration of eclipse.ini file to optimize heap sizes for adequate performance
  • User interface considered outdated compared to modern IDE alternatives
  • User base fell from 39% of Java developers in 2024 to 28% in 2025, indicating market decline

Answered from the vendors’ own pages

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.

Eclipse: How much does Eclipse IDE cost?

Eclipse IDE is completely free and open-source, released under the Eclipse Public License 2.0.

Source
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.

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.
