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 April 2026; the live site may have changed since.

Mockingbird scores well across the board, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: no Content-Security-Policy and analytics without a consent banner.

Launched on Product Hunt on April 25, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 17 technologies on this site, covering analytics, business email, baas, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 6,498 launches and more locked down than the typical Product Hunt launch.
