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 9 June 2026; the live site may have changed since.
KaroTools has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.
Launched on Product Hunt on June 9, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 2 days before launch. Our crawler found 10 technologies on this site, covering advertising, analytics, build tooling, and consent tooling. The stack includes Google Funding Choices, Vite, and GoDaddy DNS.
Notably, it's running the same core stack as 590 other launches.
