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 12 June 2026; the live site may have changed since.

Marketplace-lab scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Content-Security-Policy and no email security records.

Launched on Hacker News on June 12, 2026. The site is hosted on Amazon.com in the United States. We've detected 5 technologies on this site, covering CSS frameworks, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 7,320 launches and more locked down than the typical Hacker News launch.
