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 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.

aicaption looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 21, 2026. The site is served through Cloudflare, with a domain registered in 2016. We've detected 15 technologies on this site, covering analytics, CSS frameworks, ai service, and auth. The stack includes Bootstrap, Google Sign-In, and Tailwind CSS.

It's one of only 27 launches we've crawled running Alibaba Cloud DirectMail.
