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 10 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.

Signal0 is partway there, with a thorough launch checklist, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers and incomplete legal pages.

Launched on Product Hunt on April 6, 2026. The site is hosted on DigitalOcean in the United States. The crawl picked up 7 technologies on this site, covering DNS providers, CSS frameworks, frameworks, and meta-frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 5,872 other launches.
