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 June 2026; the live site may have changed since.

Playable City Intelligence has the basics covered well, with clean crawl signals. Main gaps: no Permissions-Policy, incomplete legal pages, and no email security records.

Launched on Hacker News on June 25, 2026. The site is hosted on Contabo GmbH in the United States, with a domain registered 4 days before launch. Our crawler found 15 technologies on this site, covering maps, package cdn, security, and analytics. The stack includes Alpine.js, Tailwind CSS, and Cloudflare.

Notably, it's one of 68 launches on this exact stack and more locked down than the typical Hacker News launch.
