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 May 2026; the live site may have changed since.

Porting my Newsletter to MCP scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and tracking cookies set before any opt-in.

Launched on Hacker News on May 25, 2026. The site is served through Cloudflare, with a domain registered in 2010. Our crawler found 11 technologies on this site, covering security, analytics, backend framework, and CDN. The stack includes Amazon Web Services, Cloudflare, and Cloudflare Bot Management.
