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 29 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.

RFC Reader still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on May 29, 2026. The site is hosted on GitHub Pages and served through Fastly. The crawl picked up 5 technologies on this site, covering CDN, CSS frameworks, frameworks, and hosting. The stack includes Tailwind CSS, Vue.js, and Fastly.

For context, it's on a stack we've seen on only 4 launches.

AI writing signals +3

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
