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

Agent 37 has the basics covered well, with complete legal pages and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 21, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2025. Our crawler found 16 technologies on this site, covering analytics, advertising, affiliate, and baas. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's running the same core stack as 8,077 other launches.
