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

Curb scores well across the board, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: no Content-Security-Policy, incomplete legal pages, and no email security records.

Launched on Hacker News on June 17, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. Our crawler found 8 technologies on this site, covering maps, DNS providers, web fonts, and hosting. The stack includes CARTO, cdnjs, and Google Fonts.

Notably, it's on one of the most common stacks we track, shared by 1,417 launches and more locked down than the typical Hacker News launch.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
