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 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.
CodeArena is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.
Launched on Product Hunt on May 28, 2026. The site is hosted on Render and served through Cloudflare, with a domain registered 9 weeks before launch. The crawl picked up 10 technologies on this site, covering baas, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, cdnjs, and Cloudflare.
For context, it's running the same core stack as 726 other 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.
