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

Seamlift is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on June 21, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 6 weeks before launch. The crawl picked up 14 technologies on this site, covering security, baas, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 8,077 other launches.
