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 24 June 2026; the live site may have changed since.
TidyCalcs — Free Online Calculators has the basics covered well, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on June 24, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. Our crawler found 12 technologies on this site, covering advertising, seo, analytics, and consent tooling. The stack includes Google Funding Choices, Bing Webmaster, and Google Ads.
Notably, it's on one of the most common stacks we track, shared by 2,264 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.
