Open-source web framework that ships zero JavaScript by default, built for content-heavy sites.
Why we recommend it
Astro produces genuinely fast sites without giving up modern component workflows, which matters directly for Core Web Vitals and search ranking.
Strengths
- Ships no JavaScript unless you ask for it
- Excellent Core Web Vitals out of the box
- Use React, Vue or Svelte components together
Drawbacks
- Requires real coding
- Less suited to highly interactive apps
