Screenshot of Hy4 preview

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 29 August 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.

Hy4 preview is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on August 29, 2026. The site is served through Tencent EdgeOne, with a domain registered in 2017. Our crawler found 5 technologies on this site, covering CDN, developer tools, business email, and transactional email. The stack includes nginx, QQ Mail, and Tencent Cloud Email.

It's also one of only 14 launches we've crawled running Tencent Cloud Email.
