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

srcset looks production-ready overall, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 18, 2026. The site is hosted on Fastly in the United States, with a domain registered 1 day before launch. We've detected 10 technologies on this site, covering analytics, baas, build tooling, and CDN. The stack includes Tailwind CSS, Vite, and Cloudflare DNS.

It's on one of the most common stacks we track, shared by 3,293 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.
