Cartlens claimed
CartLens is an AI shopping app that scans any receipt or price tag to instantly reveal if you overpaid and find cheaper local prices from real shoppers.
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 4 July 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.
Cartlens scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: tracking cookies set before any opt-in and incomplete email security.
Launched on PeerPush on May 4, 2026. The site is hosted on Vercel and served through Cloudflare. The crawl picked up 42 technologies on this site, covering javascript library, analytics, geolocation, and maps. The stack includes Clerk, Tailwind CSS, and Ahrefs.
For context, it's on one of the most common stacks we track, shared by 3,284 launches and more locked down than the typical PeerPush launch.
