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 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.

FeatherFile is largely in shape, with complete legal pages, fast page loads, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on May 19, 2026. The site is hosted on Vercel, with a domain registered 4 months before launch. The crawl picked up 11 technologies on this site, covering auth, CSS frameworks, developer tools, and DNS providers. The stack includes Google Sign-In, Tailwind CSS, and Brevo.

For context, it's on one of the most common stacks we track, shared by 3,367 launches.
