Pen Fight: flick yours, knock theirs off, keep it
The desk game from school, with real pen weights and physics you can trust. Win and the pen is yours.
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 1 September 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.
Pen Fight: flick yours, knock theirs off, keep it ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing X-Frame-Options and Content-Security-Policy and incomplete email security.
The site is served through Cloudflare, with a domain registered 1 week before launch. We've detected 13 technologies on this site, covering baas, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
It's running the same core stack as 7,712 other launches and tighter on security headers than most StackScope Discovery launches.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| 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.
