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 10 April 2026; the live site may have changed since.

I built a self-writing book on agentic coding is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on April 6, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered the day of launch. The crawl picked up 7 technologies on this site, covering CDN, cloud, DNS providers, and hosting. The stack includes Amazon Web Services, AWS CloudFront, and AWS Route 53.

For context, it's running the same core stack as 342 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.
