VERDICT

Should I use Astro?

Astro builds fast content sites, powerful web applications, dynamic server APIs, and everything in-between. - astro.build

Worth it. Use it if you have developers and a content-heavy site — it's free, open source, and developers call it fantastic. Skip it if you need no-code editing or a heavy app platform; use a website builder or Next.js instead.

Confidence

Medium. Based on ~15 usable public sources. Many 'Astro' search results were unrelated products (headsets, tires, Astro Malaysia TV, Astro by Astronomer) and were excluded.

Gotchas - check before you buy

Free software, but the real cost is developer time — agencies charge real money for builds

SSRF CVEs target host-header and server-rendered handling; keep versions current

low

Guess: mostly static sites avoid the server-side CVEs above
