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 June 2026; the live site may have changed since.

Shark has the basics covered well, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Worth fixing first: incomplete legal pages, analytics without a consent banner, and no email security records.

Launched on PeerPush on June 5, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 6 months before launch. Our crawler found 8 technologies on this site, covering analytics, build tooling, web fonts, and security. The stack includes Vite, Google Analytics, and Google Fonts.

Notably, it's running the same core stack as 650 other launches and tighter on security headers than most PeerPush launches.

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.
