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 7 July 2026; the live site may have changed since.
Markdown Arena is partway there, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Hacker News on July 7, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. The crawl picked up 5 technologies on this site, covering package cdn, CDN, DNS providers, and email forwarding. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
