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 May 2026; the live site may have changed since.

Number Lingo ships with the launch fundamentals in place, with a thorough launch checklist and clean crawl signals. What needs work: no Content-Security-Policy, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on May 5, 2026. The site is hosted on n0c, with a domain registered in 2024. Our crawler found 13 technologies on this site, covering advertising, consent tooling, analytics, and web fonts. The stack includes Google, Google Funding Choices, and cdnjs.

It's also a rare n0c sighting, just 8 in our data and tighter on security headers than most Product Hunt launches.
