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 24 August 2026; the live site may have changed since.
PropoBox ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.
Launched on Product Hunt on August 24, 2026. The site is hosted on Vercel, with a domain registered 10 weeks before launch. We've detected 21 technologies on this site, covering analytics, ai api, baas, and CMS. The stack includes Google, Next.js, and React.
It's one of 66 launches on this exact stack and tighter on security headers than most Product Hunt launches.
