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 14 July 2026; the live site may have changed since.
CSS Studio looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.
Launched on Product Hunt on July 14, 2026. The site is hosted on Google LLC in the United States, with a domain registered 6 months before launch. We've detected 10 technologies on this site, covering backend framework, DNS providers, business email, and email forwarding. The stack includes Cloudflare DNS, Express, and Google Search Console.
