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 25 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.

Valence has the basics covered well, with a thorough launch checklist, well-configured email security, and clean crawl signals. Visible gaps: missing several security headers and incomplete legal pages.

Launched on Hacker News on June 24, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2024. Our crawler found 12 technologies on this site, covering analytics, captcha, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 14,981 launches.
