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 September 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 Unlimerge — Merge Unlimited PDFs & Images, Free ships with the launch fundamentals in place, with complete legal pages and clean crawl signals. Worth fixing first: missing Permissions-Policy and Content-Security-Policy and no email security records.
The site is hosted on Netlify and served through Yandex CDN, with a domain registered 3 weeks before launch. Our crawler found 11 technologies on this site, covering advertising, transactional email, analytics, and CDN. The stack includes Google Funding Choices, Adfox, and Amazon SES.
It's also running the same core stack as 2,205 other launches and tighter on security headers than most StackScope Discovery launches.

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 |
|---|---|
| Placeholder branding | +10 |
| AI writing signals | +5 |
| AI iconography signals | +3 |
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.
