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 19 April 2026; the live site may have changed since.

PostRight ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing X-Frame-Options and Content-Security-Policy and tracking cookies set before any opt-in.

Launched on Product Hunt on April 18, 2026. The site is hosted on Netlify, with a domain registered 11 weeks before launch. The crawl picked up 13 technologies on this site, covering AI builders, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 346 other launches and tighter on security headers than most Product Hunt launches.
