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

Lyceum is partway there, with a thorough launch checklist. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Product Hunt on June 22, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 weeks before launch. The crawl picked up 11 technologies on this site, covering security, analytics, CDN, and DNS providers. The stack includes Beehiiv, Cloudflare, and Cloudflare Bot Management.

For context, it's running the same core stack as 1,225 other launches.
