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 20 April 2026; the live site may have changed since.
Rectangle Shopping + Kits ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Permissions-Policy, analytics without a consent banner, and incomplete email security.
Launched on Product Hunt on April 20, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 12 weeks before launch. Our crawler found 19 technologies on this site, covering analytics, social embeds, collaboration, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
Notably, it's running the same core stack as 6,497 other launches and tighter on security headers than most Product Hunt launches.
