Astro: Zero JavaScript by Default. Perfect Lighthouse Scores by Design.
The median web page is 2.3 MB according to HTTP Archive. Astro sites ship zero JavaScript by default and only hydrate the interactive components that need it. The result is content sites that load in under 500ms and score 100 on Lighthouse without any optimization tricks.

What's Included
Everything you get with our Astro Development
Astro Site Architecture
Content-driven site with MDX support, dynamic routes, content collections, and Islands Architecture for interactive components, all generating static HTML by default
CMS Integration
Headless CMS connection with Sanity, Storyblok, or Contentful providing content editing capabilities while Astro generates the fast static output
Edge Deployment and Performance Verification
Deployment to Vercel, Netlify, or Cloudflare Pages with CDN caching, image optimization, and Lighthouse CI verification ensuring perfect scores are maintained
Our Astro Development Process
Content Architecture and CMS Design
We design content collections, page types, and the CMS integration. Content models are structured for Astro's static generation while giving editors full content management capability.
Site Development
We build the Astro site with component-based templates, MDX support for rich content, dynamic routes for collections, and Islands Architecture for interactive components.
CMS Integration and Content Migration
We connect the headless CMS, build preview functionality, and migrate existing content. Editors can update content through the CMS while Astro generates the fast static output.
Deployment and Performance Verification
We deploy to edge hosting, configure CDN caching and image optimization, run Lighthouse CI to verify performance scores, and set up monitoring for ongoing performance tracking.
Key Benefits
Zero JavaScript by default
Static HTML pages with no JavaScript runtime. No framework overhead, no hydration delay, no JavaScript parsing time. Content renders instantly. Interactive components hydrate independently through Islands Architecture.
Perfect Lighthouse scores without optimization tricks
Astro's static output naturally scores 100 on Performance, Accessibility, Best Practices, and SEO in Lighthouse. These are not optimized-for scores; they are the default output of a well-built Astro site.
Use any framework for interactive islands
Need a React search component? A Vue carousel? A Svelte form? Astro lets you use any framework for the interactive parts of your page while the rest stays as zero-JS static HTML. Your team uses the framework they know best.
Research & Evidence
Backed by industry research and proven results
Web Almanac
The median web page is 2.3 MB with JavaScript being the largest contributor to page weight, and Astro's zero-JS default eliminates this entirely for static content

Page Load and Conversion
A 1-second site converts at 3x the rate of a 5-second site, and Astro's static output with edge caching routinely achieves sub-500ms loads
