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 28 August 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.
Firecrawl Developer Index 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.
Launched on Product Hunt on August 28, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2024. We've detected 38 technologies on this site, covering analytics, security, social embeds, and advertising. The stack includes Google Sign-In, Next.js, and React.
It's running the same core stack as 14,366 other launches and tighter on security headers than most Product Hunt launches.
