Own this Launch?

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 14 July 2026; the live site may have changed since.

CalculatorBoom covers some of the launch checklist, with complete legal pages. What needs work: missing several security headers, no robots.txt, and no email security records.

Launched on Product Hunt on July 14, 2026. The site is hosted on Contabo GmbH in Germany, with a domain registered 1 week before launch. Our crawler found 12 technologies on this site, covering advertising, CSS frameworks, analytics, and consent tooling. The stack includes Bootstrap, Google Funding Choices, and Tailwind CSS.

It's also running the same core stack as 135 other launches.
