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

Mm-to-inches has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Hacker News on July 5, 2026. The site is served through Cloudflare, with a domain registered 6 months before launch. Our crawler found 16 technologies on this site, covering analytics, advertising, seo, and CDN. The stack includes Google Funding Choices, Next.js, and React.

It's also running the same core stack as 3,329 other launches.
