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 13 August 2026; the live site may have changed since.

Gas And Chemical Delivery System 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 August 13, 2026. The site is served through Cloudflare, with a domain registered 12 weeks before launch. The crawl picked up 14 technologies on this site, covering wordpress plugin, javascript library, analytics, and CDN. The stack includes CookieYes, WooCommerce, and WordPress.

For context, it's on one of the most common stacks we track, shared by 156 launches.
