Build content-driven websites that load at the speed of light
Astro is the all-in-one web framework designed for speed. It delivers zero-JS pages by default, giving you instant loads, best-in-class SEO, and a superior developer experience — all while letting you use your favourite UI components.
Key highlights
What makes Astro the ultimate framework for content-driven websites.
Zero JS by default
Astro renders your pages to static HTML at build time, shipping zero JavaScript by default. Pages load instantly, rank higher in search, and work on any device — even the slowest connections.
Island architecture
Astro's islands pattern lets you embed interactive components (React, Preact, Vue, Svelte, Lit, or plain JS) into otherwise static pages. Only the interactive islands ship JavaScript — the rest stays lightweight HTML.
Content-first DX
Built-in Markdown/MDX support, content collections with type safety, file-based routing, and image optimization. Astro makes content management a first-class concern — not an afterthought.
Why Astro delivers great user experiences
Speed, simplicity, and content excellence — baked into every page.
Pages that load in a blink.
Astro pre-renders every page to static HTML at build time. There's no server to wait for, no JavaScript to parse, no frameworks to boot. Your users see content instantly — on any device, on any network. This isn't just fast; it's the fastest possible approach for content-driven websites.
Interactivity when you need it, not when you don't.
Astro's island architecture means interactive components are opt-in. A search bar, a contact form, a live counter — each one is a tiny island of JavaScript in a sea of static HTML. Users get the interactivity they need without paying the performance cost of a full single-page application.
SEO that actually works.
Search engines love static HTML. Astro pages are fully server-rendered at build time, meaning every heading, every paragraph, and every meta tag is present in the initial HTML response. No JavaScript rendering needed for search engines to index your content. Combined with built-in sitemap generation and RSS feed support, Astro gives you SEO superpowers out of the box.
Content that's a joy to manage.
Astro's content collections give you type-safe Markdown and MDX frontmatter, schema validation, and automatic content APIs. Your editors work in Markdown, your developers get full type safety, and your users get beautifully rendered pages with zero runtime overhead. This is the content management workflow we use for our own website — and it's transformative.
Why we chose Astro
The framework that powers our own website — and our clients' too.
At Microbians, we eat our own dogfood. This very website is built with Astro — and it's one of the best technology decisions we've made. Astro aligns perfectly with our philosophy of shipping lean, performant, and accessible websites.
Performance is a UX feature, not a backend concern. Astro's zero-JS-by-default approach means every page on our site loads almost instantly. For a consultancy site where first impressions matter, this is huge — every millisecond counts when a potential client clicks through from search results. Astro consistently puts us at the top of Lighthouse and Core Web Vitals rankings.
We also love Astro's UI-agnostic architecture. We use Alpine.js for simple interactivity, Lit for web components, and even embed Blazor components in some projects. Astro doesn't force us into a single framework — it adapts to our tool choices. This flexibility is invaluable when working with diverse client tech stacks.
Astro's content collections and Markdown support are the reason we can maintain an extensive blog and documentation without a CMS. Our content lives in version-controlled Markdown files with schema validation, and the build pipeline generates optimized pages automatically. No database, no admin panel, no complexity — just fast pages that our team can edit in any text editor.
Where Astro fits in the stack
The frontend layer for content-driven, high-performance websites.
Marketing websites and landing pages
Astro excels at content-driven marketing sites. Combine blazing-fast page loads with interactive components (forms, testimonials sliders, FAQ accordions) using Alpine.js or Preact. Deploy anywhere — Cloudflare Pages, Netlify, Vercel, or any static host.
Blogs and documentation
Astro's content collections, built-in MDX support, and auto-generated navigation make it ideal for blogs, knowledge bases, and documentation sites. Version-controlled content, type-safe frontmatter, and automatic table of contents generation keep your docs organized and maintainable.
E-commerce storefronts
Pair Astro's static product pages with a headless commerce platform for lightning-fast storefronts. Product pages are pre-rendered for maximum SEO and load speed, while cart and checkout can use interactive islands for dynamic functionality.
Hybrid static + API applications
Astro pairs naturally with server-side APIs and Cloudflare Functions. Static pages for public content, API routes for dynamic functionality. This is the architecture we use for our own site — static marketing pages with serverless API endpoints for forms and dynamic features.
When to choose Astro
A decision framework for project leaders.

- Marketing websites, landing pages, and portfolios
