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 11 April 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.

Jaku.app still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 11, 2026. The site is hosted on Vercel, with a domain registered 5 weeks before launch. The crawl picked up 8 technologies on this site, covering AI builders, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Bolt, and Google Fonts.

For context, it's on one of the most common stacks we track, shared by 3,371 launches.
