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 11 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.
Kasspian ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: incomplete email security.
Launched on Product Hunt on June 11, 2026. The site is hosted on Fly.io and served through Cloudflare, with a domain registered 11 weeks before launch. Our crawler found 21 technologies on this site, covering email forwarding, security, ai api, and analytics. The stack includes Clerk, Next.js, and React.
It's also one of 72 launches on this exact stack and tighter on security headers than most Product Hunt launches.

Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI CSS signals | +15 |
| AI copy signals | +5 |
| AI onboarding signals | +5 |
| AI palette signals | +5 |

| AI asset signals | +10 |
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.
