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 16 July 2026; the live site may have changed since.

Effort Lab is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Hacker News on July 16, 2026. The site is served through Fastly, with a domain registered in 2025. The crawl picked up 9 technologies on this site, covering CDN, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Apple App Store.

For context, it's running the same core stack as 750 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.
