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

Renzo is partway there, with complete legal pages. Main gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on June 17, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 2 weeks before launch. The crawl picked up 6 technologies on this site, covering DNS providers, business email, transactional email, and web fonts. The stack includes Google Fonts, HSTS, and Namecheap DNS.

For context, it's on one of the most common stacks we track, shared by 1,417 launches.
