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 6 May 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.

OneClickPDF scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist.

Launched on Product Hunt on May 6, 2026. The site is hosted on Vercel, with a domain registered 10 weeks before launch. We've detected 15 technologies on this site, covering business email, advertising, analytics, and CMS. The stack includes Next.js, React, and Sanity.

It's one of 73 launches on this exact stack and more locked down than the typical Product Hunt launch.

Page title is 61 characters (advisory) Google only shows about 60 characters of the title in search results; aim for 50–60 to keep the whole thing visible.
Meta description is 170 characters (advisory) Google only shows about 155–160 characters of the description in desktop search results (less on mobile); anything past that won't appear.
