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 24 April 2026; the live site may have changed since.

Promptly covers some of the launch checklist, with complete legal pages and fast page loads. Visible gaps: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 24, 2026. The site is served through Cloudflare. Our crawler found 7 technologies on this site, covering analytics, CDN, DNS providers, and email forwarding. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
