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 26 June 2026; the live site may have changed since.
Agent Arena is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on June 26, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 4 months before launch. The crawl picked up 14 technologies on this site, covering javascript library, analytics, CDN, and cloud. The stack includes Tailwind CSS, Amazon Web Services, and AWS CloudFront.
For context, it's running the same core stack as 205 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.
