Added June 15, 2026 · Last analysed June 15, 2026 · via Hacker News · also on StackScope Discovery

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 15 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.

Sweepr ships with the basics. Main gaps: missing Permissions-Policy and Strict-Transport-Security, incomplete legal pages, and no sitemap.

Launched on Hacker News on June 15, 2026. The site is served through Cloudflare. We've detected 4 technologies on this site, covering auth, CDN, DNS providers, and protocol. The stack includes Google Sign-In, Cloudflare, and Cloudflare DNS.

It's more locked down than the typical Hacker News launch.

Vibe Score Breakdown How?

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.
