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 21 April 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.
Cosmic Agent Marketplace is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers.
Launched on Product Hunt on April 21, 2026. The site is hosted on Vercel, with a domain registered in 2014. The crawl picked up 12 technologies on this site, covering transactional email, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 14,964 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
