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

ypuf is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 23, 2026. The site is hosted on Fastly in the United States, with a domain registered in 2008. The crawl picked up 5 technologies on this site, covering CDN, DNS providers, email forwarding, and hosting. The stack includes Cloudflare DNS, Cloudflare Email Routing, and Fastly.

For context, it's running the same core stack as 1,309 other launches.
