Static-first / Performance
Why Static Websites Are Fast
Pre-render pages ahead of time so visitors do not wait for the server to assemble the same public content on every request.
Choose architecture by the job.
Static rendering is especially effective when most visitors should receive the same core page content.
Static-first is not static-only.
Astro can keep most pages pre-rendered while individual components or routes use client-side interactivity, serverless functions or on-demand rendering where the product needs it.
