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 6 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.

DevKit Lab looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on May 6, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. We've detected 7 technologies on this site, covering DNS providers, email forwarding, web fonts, and frameworks. The stack includes Next.js, React, and Cloudflare DNS.

It's running the same core stack as 3,463 other launches.
