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 14 May 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.
haru eSIM scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing Content-Security-Policy and Strict-Transport-Security, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on May 13, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. Our crawler found 11 technologies on this site, covering analytics, auth, CDN, and collaboration. The stack includes Auth.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 305 launches and more locked down than the typical Product Hunt launch.
