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
MkDocs
- No built-in versioning, which Docusaurus provides and documentation teams eventually need
- Extending past the theme means writing Python plugins
- Markdown only, so embedding interactive components is not the model

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.
SourceMkDocs: Is MkDocs free?
Yes, open source under the BSD licence. The Material theme has a free version and a paid Insiders edition.
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.
SourceMkDocs: MkDocs or Docusaurus?
MkDocs is simpler and faster to adopt, especially for Python teams. Docusaurus offers versioning, internationalisation and React components, which matter once documentation grows.
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.
SourceMkDocs: Does MkDocs support versioned docs?
Not natively. Plugins such as mike add it, where Docusaurus includes versioning in core.
