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

Foldkit ships with the basics, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on June 19, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 8 months before launch. We've detected 6 technologies on this site, covering build tooling, CSS frameworks, DNS providers, and hosting. The stack includes Tailwind CSS, Vite, and Cloudflare DNS.

It's running the same core stack as 1,627 other launches.
