Astro development for fast, content-led websites
Astro is a web framework designed for content-heavy sites. It renders pages to HTML and sends JavaScript only for the interactive parts, so marketing sites, documentation and blogs load quickly and score well on performance measures.
Astro uses an islands approach: most of the page is static HTML, and interactive components can be written in React, Vue, Svelte or other frameworks and loaded only where needed. It works well with Markdown and headless CMS content, and supports server rendering when pages must be dynamic. It is not intended for highly interactive applications with lots of client-side state; for a SaaS dashboard or complex web app, Next.js, Nuxt or a single-page application is a better fit.

Astro questions
Can non-technical staff edit an Astro site?
Yes, when it is connected to a headless CMS. Editors update content in the CMS and the site rebuilds or renders the changes automatically.
Can Astro handle forms and dynamic content?
Yes. Astro supports server rendering and server endpoints, and interactive components can be added where required, though very app-like products suit other frameworks better.
What are Astro islands?
Islands are interactive components placed inside otherwise static HTML pages. Only those components load JavaScript, so a page can have a live search box or calculator while the rest stays lightweight.
Can Astro use React, Vue or Svelte components?
Yes. Astro can render components from several UI frameworks, which is useful for reusing existing components or migrating gradually from another stack.
Why are Astro sites good for SEO?
Pages are delivered as fast, fully rendered HTML with very little JavaScript, which search engines read easily and which helps Core Web Vitals. Metadata, sitemaps and structured data are simple to control.
What kind of projects is Astro best for?
Astro suits marketing sites, blogs, documentation, content hubs and landing pages where content matters more than complex interactivity. Highly interactive applications are usually better served by a full application framework.
Can Astro render pages on the server?
Yes. As well as static builds, Astro supports server rendering for pages that need fresh or personalised data, and the two approaches can be mixed within one site.
Where can an Astro site be hosted?
Static Astro sites can be hosted on almost any CDN or static host at low cost, and server-rendered sites can run on Node.js, serverless or edge platforms. Hosting sits in your own account.
Can you migrate a WordPress site to Astro?
Yes. Content can be exported into Markdown or a headless CMS, or WordPress can remain the editing backend while Astro renders the public site. We map URLs and redirects carefully to protect search rankings.
How does Astro handle content at scale?
Astro has content collections that validate Markdown and data files against a schema, so large numbers of articles or pages stay consistent and errors are caught at build time.
