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

FileFlippers ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on Product Hunt on August 4, 2026. The site is hosted on Vercel, with a domain registered in 2025. We've detected 20 technologies on this site, covering javascript library, advertising, analytics, and APIs. The stack includes Tailwind CSS, Carbon Ads, and Cloudflare DNS.

It's running the same core stack as 2,778 other launches and tighter on security headers than most Product Hunt launches.
