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 19 June 2026; the live site may have changed since.

CalcuNotas covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 19, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 3 weeks before launch. Our crawler found 14 technologies on this site, covering advertising, analytics, CDN, and consent tooling. The stack includes Google Funding Choices, React, and Tailwind CSS.

Notably, it's on a stack we've seen on only 10 launches.
