StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 16 April 2026; the live site may have changed since.
Underbelly covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on April 16, 2026. The site is hosted on Vercel, with a domain registered 5 days before launch. Our crawler found 8 technologies on this site, covering analytics, DNS providers, business email, and frameworks. The stack includes Next.js, React, and Apple Business Connect.
It's also on one of the most common stacks we track, shared by 2,296 launches.
