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 July 2026; the live site may have changed since.
Freight Calculator Hub ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: incomplete email security.
Launched on Product Hunt on July 12, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. The crawl picked up 14 technologies on this site, covering analytics, advertising, auth, and consent tooling. The stack includes Auth.js, Google, and Next.js.
For context, it's running the same core stack as 10,048 other launches and tighter on security headers than most Product Hunt launches.
