What this service solves
Astro is a modern web framework that renders pages to plain HTML ahead of time and only ships JavaScript to the parts of a page that need it. That makes it particularly useful for content-focused and performance-conscious websites: portfolios, service businesses, marketing sites and documentation.
A custom Astro site is coded rather than assembled from a page builder, so the design is not limited by a theme and the pages stay light. It suits owners who value speed and design control and are happy to request content changes, or to edit structured content files.
