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 18 August 2026; the live site may have changed since.
e-sim.co ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: incomplete email security.
Launched on Product Hunt on August 18, 2026. The site is served through Cloudflare. Our crawler found 14 technologies on this site, covering ai api, security, affiliate, and CDN. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 5,119 other launches and tighter on security headers than most Product Hunt 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.
