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 10 April 2026; the live site may have changed since.
Penvox covers some of the launch checklist, with complete legal pages and well-configured email security. Worth fixing first: missing Permissions-Policy and Content-Security-Policy, no robots.txt or sitemap, and tracking cookies set before any opt-in.
Launched on Product Hunt on April 7, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. Our crawler found 12 technologies on this site, covering transactional email, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 10,729 other launches and tighter on security headers than most Product Hunt launches.
