Astro is an open-source web framework that renders pages to static HTML at build time and sends no JavaScript unless a component explicitly needs it. That default is the whole product: for content-driven sites, it removes the performance cost that general-purpose application frameworks impose by design.

Astro pricing
Prices below were read from the vendor's own pricing page on 9 August 2026. Pricing model: one time. No free trial is offered.
| Plan | Price | Billing | Notes |
|---|---|---|---|
| Astro framework | $0 | per one-time | MIT licensed open source. The cost is developer time, not licensing |
| Hosting | From $0 | per month | Static output hosts free on Cloudflare Pages, Netlify or Vercel Hobby |
Which Astro plan should you buy?
| Your situation | Recommended | Why |
|---|---|---|
| You are building a content site, blog or documentation | Astro framework | Free and MIT licensed. Ships no JavaScript by default, which is the whole point. |
| You want it hosted for nothing | Astro plus Cloudflare Pages or Netlify | Static output fits the free tier of every major host, so a real site can cost nothing to run. |
| You are building an application with authentication and state | Consider Next.js instead | Astro is site-first. An app with sessions and client state fits Next.js better. |
| Nobody on the team writes code | Do not choose Astro | There is no visual editor. Webflow or Squarespace exist for exactly this case. |
Verdict by who you are
Developer building a content siteYes
Free, fast by default, and framework-agnostic for components. For pages rather than apps this is the strongest choice available.
Documentation team with developer supportYes
Starlight and MDX make this one of the best documentation stacks, at no licence cost.
Product team building a web appCompare first
Possible with islands, but Next.js is the better fit once most of the page is interactive.
Marketing team with no developerNo
There is no visual editing. You need a builder, not a framework.

Our assessment
Astro made the correct default choice for the kind of site most organisations actually publish. Application frameworks ship a JavaScript runtime because they assume interactivity; Astro assumes content and adds interactivity only where you ask for it, which is why an Astro marketing site routinely outperforms the same site built in a general framework without anyone optimising anything. Content collections with schema validation are the other quietly important feature, because they make a large Markdown-based site enforceable rather than hopeful. The requirement is a developer, and that is a genuine disqualifier for some teams rather than a detail.
What works in Astro
- No JavaScript shipped unless a component needs it
- Content collections validate structured content at build time
- Framework-agnostic, so existing React or Vue components still work
- Free, open source, and hosts free on several platforms
What doesn't
- Requires someone comfortable with a code editor and Git
- Not the right tool for genuinely interactive applications
- No visual editor, so content people need Markdown or a CMS
- Smaller ecosystem than the largest application frameworks

The disclosure
EveryAny.One is built with Astro and deployed to Cloudflare Pages, so treat the rating accordingly. We would rather state that plainly than pretend to neutrality we do not have. The reasoning is in our methodology: this site needs unlimited content, server-rendered HTML and fast pages, which is precisely the case Astro is built for, and precisely what rules out every visual builder we also cover.
Your requirements are probably different. Most organisations should not build their marketing site in code.
What “zero JavaScript by default” actually buys
A typical marketing page built with an application framework ships a framework runtime, a router and hydration data before it renders anything. Astro renders to HTML at build time and ships nothing unless you mark a component as interactive. The practical result is that performance is the starting condition rather than an optimisation project, which matters for Core Web Vitals and, increasingly, for whether AI crawlers can read your content at all.
Content collections are the underrated feature
Astro can validate your Markdown frontmatter against a schema at build time. That sounds administrative until you run a site with dozens of structured pages: a missing price, a malformed date or an absent verification field fails the build rather than publishing quietly. On this site that check is the reason fact tables can be trusted, and it is the feature we would miss most.
The real cost
Astro is free. Building with it is not. Budget developer time for the initial build and a small amount of ongoing maintenance, and be honest about who will edit content: Markdown in a repository suits engineers and frustrates marketers. Pairing Astro with a headless CMS solves that and adds cost, at which point Webflow deserves a fair comparison.
Hosting is the free part
Static output hosts at no cost on Cloudflare Pages, and on Netlify or Vercel Hobby for non-commercial use. For a commercial site on Cloudflare Pages, static requests remain unmetered, which is why the combination is the cheapest credible option in our website builders guide.
