Harfi
A game where you write the instruction, not the answer. Forty trials, each a spec an AI's output must hit exactly — checked by a parser, never by an opinion.

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 18 August 2026; the live site may have changed since.
Harfi ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing Permissions-Policy and Content-Security-Policy and incomplete email security.
Launched on Product Hunt on August 18, 2026. The site is hosted on Vercel, with a domain registered 2 days before launch. The crawl picked up 8 technologies on this site, covering analytics, baas, DNS providers, and frameworks. The stack includes Next.js, React, and Firebase.
For context, it's running the same core stack as 3,024 other launches and tighter on security headers than most Product Hunt launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
