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 6 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.

LightShadow: 16-bit Photo Resizer still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 6, 2026. The site is served through Alibaba Cloud CDN, with a domain registered in 2020. The crawl picked up 6 technologies on this site, covering analytics, CDN, cloud, and DNS providers. The stack includes Alibaba Cloud, Alibaba Cloud CDN, and Baidu Tongji.
