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 23 July 2026; the live site may have changed since.
RFI Know scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on July 23, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 11 months before launch. The crawl picked up 25 technologies on this site, covering analytics, storage, ui library, and advertising. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
For context, it's on one of the most common stacks we track, shared by 278 launches and more locked down than the typical Product Hunt launch.
