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 13 April 2026; the live site may have changed since.
Call Flow scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on April 1, 2026. The site is hosted on Fly.io and served through Cloudflare, with a domain registered 2 days before launch. The crawl picked up 15 technologies on this site, covering transactional email, security, seo, and AI builders. The stack includes Tailwind CSS, Amazon SES, and Cloudflare.
For context, it's one of 62 launches on this exact stack.
