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 30 June 2026; the live site may have changed since.
MailCull ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on June 30, 2026. The site is served through Cloudflare. Our crawler found 14 technologies on this site, covering analytics, advertising, backend framework, and CDN. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
It's also tighter on security headers than most Product Hunt launches.
