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

Sub Rosa ships with the basics, with complete legal pages and a thorough launch checklist. Worth fixing first: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on June 25, 2026. The site is hosted on Contabo Inc. in the United States, with a domain registered 7 weeks before launch. We've detected 11 technologies on this site, covering analytics, consent tooling, CSS frameworks, and DNS providers. The stack includes Google, Next.js, and React.

It's running the same core stack as 2,990 other launches.
