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

QuickMark is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Hacker News on July 27, 2026. The site is served through Cloudflare, with a domain registered 9 weeks before launch. The crawl picked up 5 technologies on this site, covering CDN, DNS providers, email forwarding, and protocol. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
