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 11 April 2026; the live site may have changed since.
Blue eSIM ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Permissions-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on April 10, 2026. The site is hosted on Vercel, with a domain registered in 2024. Our crawler found 21 technologies on this site, covering advertising, business email, social embeds, and analytics. The stack includes Auth.js, Next.js, and React.
It's also running the same core stack as 10,671 other launches and tighter on security headers than most Product Hunt launches.
