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 26 May 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.

Firmbase: Claude for UK B2B prospecting ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on May 26, 2026. The site is served through Cloudflare. The crawl picked up 12 technologies on this site, covering AI builders, analytics, CDN, and CSS frameworks. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

For context, it's running the same core stack as 7,711 other launches.
