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 28 August 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.

PostShelf ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy and incomplete email security.

Launched on Product Hunt on August 28, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered 3 days before launch. We've detected 16 technologies on this site, covering social embeds, security, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 986 other launches and tighter on security headers than most Product Hunt launches.
