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 15 June 2026; the live site may have changed since.
oneshekel.com is partway there, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on June 15, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2021. The crawl picked up 11 technologies on this site, covering advertising, analytics, consent tooling, and DNS providers. The stack includes Gatsby, Google Funding Choices, and Google Ads.
For context, it's one of only 19 launches we've crawled running Gatsby.

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.
