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.

Islo.dev has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on June 21, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 4 months before launch. Our crawler found 8 technologies on this site, covering analytics, CDN, cloud, and DNS providers. The stack includes Amazon Web Services, AWS CloudFront, and AWS Route 53.

Notably, it's on one of the most common stacks we track, shared by 267 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.
