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 29 April 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.
Doudou-chinese covers some of the launch checklist, with complete legal pages. Visible gaps: missing Permissions-Policy and Content-Security-Policy, no robots.txt or sitemap, and incomplete email security.
Launched on Hacker News on April 29, 2026. The site is hosted on DigitalOcean in the United States, with a domain registered 5 months before launch. Our crawler found 7 technologies on this site, covering DNS providers, business email, email marketing, and web fonts. The stack includes DigitalOcean DNS, Google Fonts, and HSTS.
It's also more locked down than the typical Hacker News launch.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI palette signals | +5 |
| AI writing signals | +5 |
| AI layout 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.
