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 29 June 2026; the live site may have changed since.
Relationship Builder Pro has the basics covered well, with complete legal pages and a complete set of security headers. Main gaps: no robots.txt or sitemap and incomplete email security.
Launched on Product Hunt on June 29, 2026. The site is hosted on Vercel, with a domain registered 3 months before launch. Our crawler found 17 technologies on this site, covering communication, transactional email, ai api, and baas. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 8,807 launches and more locked down than the typical Product Hunt launch.
