An experimental Forward Deployed Agent by Firecrawl.

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 June 2026; the live site may have changed since.

Prometheus by Firecrawl looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and analytics without a consent banner.

Launched on Product Hunt on June 13, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2024. We've detected 12 technologies on this site, covering transactional email, analytics, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 7,381 launches.
