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 19 June 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.

CleanSheet AI is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 19, 2026. The site is hosted on Firebase App Hosting and served through Cloudflare, with a domain registered in 2025. The crawl picked up 22 technologies on this site, covering advertising, email marketing, hosting, and security. The stack includes Tailwind CSS, Bing Webmaster, and Cloudflare.

For context, it's the only launch we've crawled on this exact stack.

Page title is 72 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 189 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.
