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 13 April 2026; the live site may have changed since.
Lightning V3 ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers and tracking cookies set before any opt-in.
Launched on Product Hunt on April 2, 2026. The site is served through AWS CloudFront, with a domain registered in 2023. We've detected 19 technologies on this site, covering analytics, advertising, seo, and AI builders. The stack includes Amazon Web Services, AWS CloudFront, and AWS Route 53.
