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 9 June 2026; the live site may have changed since.

Rumlin is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on June 9, 2026. The site is hosted on Cloudflare in the United States. The crawl picked up 10 technologies on this site, covering CSS frameworks, CDN, DNS providers, and business email. The stack includes Bootstrap, Tailwind CSS, and Cloudflare.

For context, it's one of 45 launches on this exact stack.
