Own this Launch?

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 June 2026; the live site may have changed since.

Rubtin looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.

Launched on Product Hunt on June 19, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 10 weeks before launch. We've detected 13 technologies on this site, covering analytics, CDN, consent tooling, and CSS frameworks. The stack includes Google, Next.js, and React.

It's on one of the most common stacks we track, shared by 201 launches.
