The short version
- Each has a real cost: Docusaurus customisation past the config file assumes React knowledge, which not every docs team has; Express.js governed by the OpenJS Foundation with no vendor or paid tier, per expressjs.com; as open source software it has no pricing to compare

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
Express.js
- Governed by the OpenJS Foundation with no vendor or paid tier, per expressjs.com; as open source software it has no pricing to compare
- Express.js provides only a thin layer of fundamental routing features by its own description, requiring separate middleware modules for functionality like body parsing, sessions or authentication

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.
Express.js: Is Express.js free?
Yes, Express.js is completely free and open source. The framework is maintained by the OpenJS Foundation and available via npm at no cost. Installation is as simple as running npm install express.
SourceDocusaurus: 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.
Express.js: Does Express.js offer commercial support?
Express.js itself is free with no official commercial support from the project. Community support is available through documentation and community resources at no cost. Third-party vendors may offer commercial support services, though none are listed on the official website.

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.
