Subscription Index
Weekly pricing, conversion, retention, and expansion strategies for subscription businesses. From the operator who grew Codecademy from $10M to $50M ARR.
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 12 April 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.
Subscription Index is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: no Content-Security-Policy, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on PeerPush on April 9, 2026. The site is hosted on Vercel, with a domain registered in 2023. The crawl picked up 8 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.
For context, it's running the same core stack as 15,030 other launches and tighter on security headers than most PeerPush launches.

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.
