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 30 June 2026; the live site may have changed since.
Preflight looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.
Launched on Product Hunt on June 30, 2026. The site is hosted on Vercel. We've detected 9 technologies on this site, covering ui library, analytics, CSS frameworks, and frameworks. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 8,975 other launches.
