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 8 May 2026; the live site may have changed since.

Sharkspeare is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on May 8, 2026. The site is hosted on Vercel, with a domain registered 12 weeks before launch. Our crawler found 6 technologies on this site, covering auth, CSS frameworks, frameworks, and hosting. The stack includes Auth.js, Next.js, and React.

It's also running the same core stack as 14,130 other 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.
