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 25 July 2026; the live site may have changed since.

RockFocus scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on July 25, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. We've detected 5 technologies on this site, covering DNS providers, business email, hosting, and mobile. The stack includes Alibaba Cloud, Alibaba Mail, and Apple App Store.

It's on one of the most common stacks we track, shared by 3,179 launches.
