fei.io v2

I build interfaces people remember — where every interaction feels intentional, the code reads like prose, and the engineering behind it holds up under pressure.

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.

fei.io v2 is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on April 1, 2026. The site is served through Cloudflare. The crawl picked up 7 technologies on this site, covering analytics, CDN, developer tools, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Web Analytics.
