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 June 2026; the live site may have changed since.

Mosaci has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, placeholder text in the legal pages, and incomplete email security.

Launched on Product Hunt on June 25, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. Our crawler found 10 technologies on this site, covering analytics, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's on one of the most common stacks we track, shared by 8,555 launches.
