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 15 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.
Costhawk ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: tracking cookies set before any opt-in and incomplete email security.
Launched on Hacker News on May 15, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 9 months before launch. The crawl picked up 21 technologies on this site, covering analytics, advertising, security, and seo. The stack includes Clerk, Next.js, and React.
For context, it's running the same core stack as 593 other launches and tighter on security headers than most Hacker News launches.
