Astro Jamstack marketing site rebuild

About the project

A US-based Series-B B2B SaaS had a marketing site built as a single-page React app. The site served the company well in its early days, but as the product matured the marketing team needed faster iteration and the slow initial load was costing conversions. We rebuilt the site as an Astro Jamstack application. The result was a statically generated site that loaded in under 1.5 seconds, scored 98 on Lighthouse performance, and gave the content team full control over page structure without touching code. This astro jamstack case study shows how a focused frontend rebuild can pay off across both engineering and marketing goals.

Background

The existing React SPA shipped a large JavaScript bundle on every visit, even for pages with no interactive elements. A third-party analytics script and an embedded demo widget pushed LCP past four seconds on mid-range devices. The marketing team had to file tickets for layout changes and waited days for deploys. The company was preparing a Series-B announcement and needed the site to perform under a traffic spike.

What we built

A statically generated Astro Jamstack site with zero-JS pages, partial hydration, and a block-based content model for the marketing team.

Static Astro build Icon

Static Astro build

Every marketing page is pre-rendered at build time. Pages contain no client-side JavaScript unless a section explicitly needs it, which keeps payload sizes small and Time to First Byte under 200ms.

Partial hydration islands Icon

Partial hydration islands

Interactive elements such as the pricing calculator and the demo request form are hydrated as Astro islands. The rest of the page is pure HTML and CSS, so the browser does minimal parse work.

Block-based page composer Icon

We built a library of fifteen reusable section blocks: hero, feature grid, testimonial strip, pricing table, and more. The marketing team assembles new pages by combining blocks in a YAML content file, with no code changes required.

CI and edge deploy pipeline Icon

CI and edge deploy pipeline

A GitHub Actions workflow runs the Astro build on every push to the main branch, validates internal links, and deploys the prebuilt output to the CDN. A full rebuild and deploy completes in about four minutes.

Takeaway

This astro jamstack case study shows that a marketing site rebuild does not have to be a months-long project. When the existing site is a JavaScript-heavy SPA and the content is largely static, switching to Astro and a block-based content model is a focused, well-scoped engagement. The payoff is a site that loads faster, ranks better, and gives the marketing team the autonomy they need to move at product speed. We bring the same approach to any growth-stage software company looking to ship a performant, maintainable marketing presence.
