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

CalcKong financial calculators ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: no email security records.

Launched on Product Hunt on July 20, 2026. The site is hosted on Zeabur, with a domain registered 2 weeks before launch. We've detected 17 technologies on this site, covering advertising, consent tooling, data api, and affiliate. The stack includes Google, Google Funding Choices, and Next.js.

It's a rare Zeabur sighting, just 20 in our data and tighter on security headers than most Product Hunt launches.
