StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 21 May 2026; the live site may have changed since.
Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.
AstroSend looks production-ready overall, with complete legal pages and a thorough launch checklist. Main gaps: missing several security headers, no robots.txt, and incomplete email security.
Launched on Product Hunt on May 21, 2026. The site is hosted on Vercel, with a domain registered in 2020. We've detected 10 technologies on this site, covering AI builders, auth, CSS frameworks, and DNS providers. The stack includes Auth.js, Next.js, and React.
It's on one of the most common stacks we track, shared by 14,978 launches.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI CSS signals | +10 |
| AI writing signals | +5 |

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
