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

GPX Flight Replays looks production-ready overall, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and analytics without a consent banner.

Launched on Hacker News on June 3, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 7 months before launch. We've detected 9 technologies on this site, covering analytics, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 6,507 other launches.
