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 31 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.

ExcelFormulaAI is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on August 31, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 10 technologies on this site, covering advertising, analytics, consent tooling, and developer tools. The stack includes Google Funding Choices, cdnjs, and Google AdSense.

For context, it's running the same core stack as 4,158 other launches.
