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 15 June 2026; the live site may have changed since.
RoastUI.ai has the basics covered well, with a thorough launch checklist and clean crawl signals. Visible gaps: no Content-Security-Policy, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on June 15, 2026. The site is hosted on IONOS SE in Germany, with a domain registered 6 weeks before launch. Our crawler found 9 technologies on this site, covering auth, CSS frameworks, DNS providers, and transactional email. The stack includes Auth.js, Next.js, and React.
Notably, it's on one of the most common stacks we track, shared by 2,578 launches and more locked down than the typical Product Hunt launch.
