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

SQLMarrow is largely in shape, 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 23, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 months before launch. The crawl picked up 17 technologies on this site, covering advertising, seo, analytics, and consent tooling. The stack includes Google Funding Choices, Next.js, and React.

For context, it's on one of the most common stacks we track, shared by 8,317 launches.
