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 21 April 2026; the live site may have changed since.

JetOpti looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on April 21, 2026. The site is hosted on IONOS, with a domain registered 5 months before launch. We've detected 9 technologies on this site, covering hosting, developer tools, DNS providers, and business email. The stack includes Google Fonts, Google Tag Manager, and HSTS.

It's one of 30 launches on this exact stack.
