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 25 June 2026; the live site may have changed since.
Calculators Labs has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.
Launched on Product Hunt on June 25, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 months before launch. Our crawler found 9 technologies on this site, covering advertising, analytics, consent tooling, and DNS providers. The stack includes Google Funding Choices, Google Ads, and Google AdSense.
Notably, it's on one of the most common stacks we track, shared by 2,295 launches.
