ASTRO SERVICES

Astro websites, built by senior engineers.

Marketing sites, documentation estates, multilingual portals, and headless front-ends on Sitecore, Contentful, Sanity, Storyblok, Strapi, Keystatic, or TinaCMS — shipped on Astro with islands architecture, zero JS by default, and a build pipeline tuned for editor velocity.

Why Astro

Fast pages aren't a feature.
They're the product.

For content-heavy sites

Most JS frameworks ship React (or Vue, or Svelte) to the browser whether the page needs it or not. On marketing sites, blog estates, documentation portals, and multilingual brand sites, that's wasted bytes on every visit — and seconds added to LCP on mobile.

Astro renders to HTML by default and only hydrates the islands that actually need JavaScript. Same content, same CMS, fewer bytes — and Lighthouse scores that hold up on real devices, not just the dev's MacBook.

How we engage

Five ways to bring us in.

Whether you need a greenfield build, a migration off a heavier stack, a two-week audit, a headless front-end on Contentful, Sanity, Sitecore, Storyblok, Strapi, Keystatic, or TinaCMS, or just an experienced pair of hands on retainer — you get the same senior Astro team.

SITECORE ASTRO SDK

Sitecore-headless on Astro — finally fast.

Only a handful of companies in the world build their own SDK for Sitecore — we're one of them. Our Astro SDK ships Sitecore-headless sites with islands architecture, partial hydration, and a build pipeline tuned for editor velocity. Same Layout Service, same personalization, a fraction of the JS.

  • Layout Service + Experience Edge
  • Astro islands + view transitions
  • JSS and Content SDK compatibility

The stack

Astro at the front, every modern CMS at the back.

Astro is the front-end. Around it: any headless CMS, any major UI framework for islands, every edge host worth deploying to, and an AI layer your engineers will actually use.

Frequently asked

The questions Astro leads bring to us.

For content-heavy sites — marketing, documentation, blog estates, multilingual brand portals — Astro ships zero JS by default and only hydrates the islands that actually need it. The Next.js default is the opposite: React on every page, whether the page needs it or not. On our Sitecore benchmark, Astro beat the Next.js Content SDK reference by +30 Lighthouse points and 3.2 seconds of LCP on mobile. For app-shaped UIs Next.js is still a fine choice — we ship both.

Yes. We do page-for-page migrations — preserving URLs, redirects, structured data, and editor workflows. Typical engagement: 4–10 weeks for a 30-page marketing site, longer for content estates with hundreds of templates. We can keep WordPress as the editing CMS and let Astro render the front-end, or move the content into a modern headless CMS at the same time.

No. The Sitecore Astro SDK is our proof of depth — we maintain it because our own engineers needed it — but our Astro work spans every kind of content-heavy site. Marketing sites, documentation portals, multilingual brand estates, e-commerce frontends, retainer support. The SDK is the moat; the practice is broader.

Two weeks from first call to senior engineers in the codebase, typical. For audits and rescues we start with a paid two-week diagnostic: profile the site, identify the top wins, hand back a re-baselined plan. After that, you decide whether we ship the rest or take the plan and run.

Yes — it's free to use forever. We built it because our own engineers needed it. If you want help integrating it into your team's headless workflow, that's where consulting comes in.
