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 3 September 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.

Agent Builder by Airtop is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on September 3, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2024. The crawl picked up 29 technologies on this site, covering advertising, analytics, sales intelligence, and security. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 14,963 other launches.
