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

rubarb.bar ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on Product Hunt on June 11, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 2 weeks before launch. Our crawler found 9 technologies on this site, covering business email, seo, CDN, and DNS providers. The stack includes Apple Business Connect, Apple iCloud Mail, and Cloudflare.

Notably, it's tighter on security headers than most Product Hunt launches.
