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

Investor Calculators covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on April 7, 2026. The site is hosted on WIX_COM in Israel, with a domain registered 2 days before launch. Our crawler found 10 technologies on this site, covering seo, advertising, AI builders, and analytics. The stack includes React, Ahrefs, and Bing Webmaster.

It's also on one of the most common stacks we track, shared by 288 launches.
