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 August 2026; the live site may have changed since.

Crammed ships with the basics, with a thorough launch checklist, well-configured email security, and clean crawl signals. Visible gaps: missing several security headers and incomplete legal pages.

Launched on Hacker News on August 18, 2026. The site is hosted on Railway, with a domain registered 1 week before launch. We've detected 7 technologies on this site, covering backend framework, developer tools, DNS providers, and email forwarding. The stack includes Cloudflare DNS, Cloudflare Email Routing, and Express.

It's on one of the most common stacks we track, shared by 610 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.
