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 25 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.
PDF Pro — Private PDF Tools ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.
Launched on Product Hunt on April 25, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 13 technologies on this site, covering auth, baas, collaboration, and CSS frameworks. The stack includes Google OAuth, Google Sign-In, and Svelte.
For context, it's on a stack we've seen on only 4 launches and tighter on security headers than most Product Hunt launches.

Readiness Breakdown How?
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI copy signals | +5 |
| AI palette signals | +5 |
| AI writing signals | +5 |
| AI code-structure signals | +5 |
| Recognised AI builder signature | +30 |
| AI CSS signals | +15 |
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.
