The short version

  • Each has a real cost: Astro limited to static site generation and server-side rendering; real-time applications requiring constant client-server communication are unsuitable; Docusaurus customisation past the config file assumes React knowledge, which not every docs team has

Where each one falls short

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

Astro

  • Limited to static site generation and server-side rendering; real-time applications requiring constant client-server communication are unsuitable
  • Smaller ecosystem compared to Next.js; fewer third-party component libraries and integrations readily available
  • Build time increases with large content volumes (1,000+ pages); incremental builds not yet as optimised as Gatsby or Next.js
  • API routes and serverless functions are less mature than Next.js; complex backend integrations require additional tooling

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

Astro: Is Astro free?

Yes. Astro is free and open-source under MIT licence. Deployment hosting (Vercel, Netlify, Cloudflare, AWS) may incur costs depending on usage.

Source
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.

Astro: Can I use React components in Astro?

Yes. Astro supports React, Vue, Svelte, Preact, and Solid components. Components are server-rendered by default; add client: directives to enable client-side interactivity only where needed.

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.

Astro: How does Astro compare to Next.js for performance?

Astro achieves superior Core Web Vitals scores (66% pass rate vs Next.js 30%) by shipping minimal JavaScript. Next.js defaults to client-side rendering; Astro renders on the server by default.

Source
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.
