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

DebtCalc covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on June 13, 2026. The site is hosted on Fastly in the United States. Our crawler found 9 technologies on this site, covering advertising, CDN, consent tooling, and web fonts. The stack includes Google Funding Choices, cdnjs, and Fastly.

Notably, it's on one of the most common stacks we track, shared by 1,057 launches.
