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 16 June 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.
Caption Room scores highly overall, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: no Content-Security-Policy, incomplete legal pages, and no email security records.
Launched on Product Hunt on June 16, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. The crawl picked up 12 technologies on this site, covering auth, analytics, captcha, and CDN. The stack includes Auth.js, Google Sign-In, and Next.js.
For context, it's on one of the most common stacks we track, shared by 5,873 launches and more locked down than the typical Product Hunt launch.

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.
