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 24 June 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.
seedance 2.5 looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on June 24, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 1 day before launch. We've detected 14 technologies on this site, covering analytics, security, auth, and CDN. The stack includes Clerk, Next.js, and React.
It's running the same core stack as 15,004 other launches.

Vibe Score Breakdown How?
| Signal | Points |

| AI palette signals | +5 |
| AI stack signals | +10 |
| Implausible social-proof claim | +15 |

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.
