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

Sabela is partway there. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Hacker News on June 14, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 10 weeks before launch. The crawl picked up 1 technology on this site, covering servers. The stack includes Warp.

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.
