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 15 July 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.

Jointjs has the basics covered well, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on July 15, 2026. The site is served through Cloudflare, with a domain registered in 2009. Our crawler found 27 technologies on this site, covering javascript library, package cdn, transactional email, and affiliate. The stack includes Amazon, Cookiebot, and Anime.js.

It's also a rare Amazon sighting, just 49 in our data.
