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 21 July 2026; the live site may have changed since.

Firecalculatorhq has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers and no email security records.

Launched on Hacker News on July 20, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. Our crawler found 9 technologies on this site, covering security, analytics, CDN, and DNS providers. The stack includes Beehiiv, Chart.js, and Cloudflare.
