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

Bluedoor covers some of the launch checklist, with well-configured email security, fast page loads, and clean crawl signals. Visible gaps: missing several security headers and incomplete legal pages.

Launched on Hacker News on June 8, 2026. The site is hosted on Cloudflare in the United States. Our crawler found 11 technologies on this site, covering CDN, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Cloudflare.

Notably, it's on one of the most common stacks we track, shared by 1,457 launches.
