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 April 2026; the live site may have changed since.

Yumi ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.

Launched on Hacker News on April 25, 2026. The site is served through Cloudflare, with a domain registered 6 months before launch. Our crawler found 8 technologies on this site, covering CDN, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's also running the same core stack as 5,948 other launches.
