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

DNLeads B2B Leads ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy and incomplete email security.

Launched on Product Hunt on August 18, 2026. The site is served through Cloudflare. The crawl picked up 17 technologies on this site, covering security, ui library, analytics, and auth. The stack includes Clerk, Google, and Tailwind CSS.

For context, it's running the same core stack as 7,092 other launches and tighter on security headers than most Product Hunt launches.
