Own this Launch?

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 18 July 2026; the live site may have changed since.

GraphChinese is partway there, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on July 18, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 5 days before launch. The crawl picked up 6 technologies on this site, covering servers, DNS providers, web fonts, and seo. The stack includes Caddy, Cloudflare DNS, and Google Fonts.
