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 30 August 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.

Winnow is early-stage. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on August 30, 2026. The site is served through Cloudflare. We've detected 7 technologies on this site, covering meta-frameworks, CDN, CSS frameworks, and developer tools. The stack includes Next.js, React, and Tailwind CSS.

It's on a stack we've seen on only 17 launches.
