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 14 July 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.

Anvil SDK looks production-ready overall, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on July 14, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 4 months before launch. We've detected 11 technologies on this site, covering analytics, captcha, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 14,964 launches.
