Why we chose Astro for callr.com
· The Callr Team
Performance matters for a developer-facing product. Astro lets us author pages as mostly-static HTML and opt into client-side interactivity per component.
Islands, not bundles
Instead of shipping a single large JavaScript bundle, Astro hydrates only the components that need it. For Callr, that means our marketing pages stay light while interactive widgets — like pricing calculators — load on demand.
This is the architecture that powers the page you’re reading right now.
