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 12 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.
Rtrvr has the basics covered well, with complete legal pages and a thorough launch checklist. Main gaps: missing several security headers, no robots.txt, and incomplete email security.
Launched on Hacker News on April 12, 2026. The site is hosted on Vercel, with a domain registered in 2023. Our crawler found 18 technologies on this site, covering advertising, transactional email, analytics, and baas. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 15,005 launches.

Readiness Breakdown How?
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI CSS signals | +10 |
| 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.
