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 17 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.
Rental ROI Calculator scores highly overall, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Main gaps: incomplete legal pages, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on June 17, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. We've detected 14 technologies on this site, covering advertising, analytics, auth, and CSS frameworks. The stack includes Auth.js, Next.js, and React.
It's on one of the most common stacks we track, shared by 14,964 launches and more locked down than the typical Product Hunt launch.

Readiness Breakdown How?
Performance How?
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 writing signals | +3 |
| AI iconography signals | +3 |
| Default scaffold favicon | +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.
