Added August 29, 2026 · Last analysed August 30, 2026 · via StackScope Discovery · also on Product Hunt

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 30 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.

SocialPostMockup ships with the basics, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.

The site is hosted on Vercel. We've detected 8 technologies on this site, covering analytics, CSS frameworks, DNS providers, and web fonts. The stack includes Tailwind CSS, Google Fonts, and Google Search Console.

It's running the same core stack as 3,376 other launches.
