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

Sf-voice covers some of the launch checklist, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Hacker News on June 19, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 9 technologies on this site, covering CSS frameworks, DNS providers, business email, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's running the same core stack as 7,957 other launches.
