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 2 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.
PDF Offline is partway there, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on June 2, 2026. The site is served through Cloudflare, with a domain registered in 2025. The crawl picked up 10 technologies on this site, covering analytics, AI builders, CDN, and CSS frameworks. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
For context, it's on one of the most common stacks we track, shared by 7,712 launches.

Readiness Breakdown How?
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI writing signals | +5 |
| Recognised AI builder signature | +100 |
| 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.
