Own this Launch?
Screenshot of Leash

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 June 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.

Leash still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 10, 2026. The site is hosted on Hetzner Online GmbH in Germany. The crawl picked up 6 technologies on this site, covering mobile, DNS providers, business email, and web fonts. The stack includes Apache, Apple App Store, and Google Fonts.
