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 20 June 2026; the live site may have changed since.
PerformSpark looks production-ready overall, 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 20, 2026. The site is hosted on Cloudflare London in the United States, with a domain registered 6 months before launch. We've detected 19 technologies on this site, covering analytics, security, package cdn, and seo. The stack includes Apollo.io, Bing Webmaster, and Cloudflare.
