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 April 2026; the live site may have changed since.
RankFast scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: no Permissions-Policy and tracking cookies set before any opt-in.
Launched on Product Hunt on April 23, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. We've detected 22 technologies on this site, covering analytics, advertising, business email, and social embeds. The stack includes Next.js, React, and Tailwind CSS.
It's on one of the most common stacks we track, shared by 3,885 launches and more locked down than the typical Product Hunt launch.
