The short version

Only Astro has a free tier, so it costs nothing to try first.
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; Redocly only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it

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

Redocly

Only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
The portal and governance features are paid, while the open-source renderer covers only reference rendering
Linting rules are another thing to configure and argue about before value appears
Narrower than a general documentation platform, by design

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

Redocly: Is Redocly free?

The Redoc renderer and CLI are open source and free. The developer portal and governance features are paid, with pricing published on the vendor site.

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

Redocly: What does the linter do?

It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.

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

Redocly: Do I need OpenAPI to use it?

Effectively yes. Without a maintained specification there is little for it to work with.
