毎日1問!👔と🍺を並べる論理パズル。バランスよく定時退社しよう。

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

定時退社タンゴ is partway there, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 16, 2026. The site is hosted on Fastly in the United States, with a domain registered 1 week before launch. The crawl picked up 6 technologies on this site, covering analytics, CDN, DNS providers, and hosting. The stack includes Cloudflare DNS, Cloudflare Web Analytics, and Fastly.

For context, it's running the same core stack as 1,116 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.
