Posthorn
Posthorn is an agent-native CLI that spins up cold-email infrastructure: sending domains, DNS auth, mailboxes, and inbox warmup, on accounts you own. Built to be operated by AI agents.
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 10 June 2026; the live site may have changed since.
Posthorn is early-stage. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Hacker News on June 10, 2026. The site is hosted on Railway in the United States. We've detected 5 technologies on this site, covering DNS providers, business email, web fonts, and hosting. The stack includes Cloudflare DNS, Google Fonts, and Google Search Console.
It's running the same core stack as 198 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
