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

Bcad ships with the basics. Visible gaps: no Permissions-Policy, incomplete legal pages, and no sitemap.

Launched on Hacker News on June 28, 2026. The site is hosted on The Constant Company in the United States. We've detected 3 technologies on this site, covering DNS providers, security, and servers. The stack includes HSTS, nginx, and Vultr DNS.

It's more locked down than the typical Hacker News launch.
