Flatnine
At AI week, Gian Segato mentioned that people inside Anthropic keep their own personal eval for Claude: a small, private test they trust more than any leaderboard. That idea stuck with me, so I built mine out of the thing I trust my own taste on most: Charlie Parker solos.
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 9 June 2026; the live site may have changed since.
Flatnine is largely in shape, with a complete set of security headers and a thorough launch checklist. Visible gaps: incomplete legal pages, no sitemap, and incomplete email security.
Launched on Hacker News on June 9, 2026. The site is hosted on Cloudflare in the United States. The crawl picked up 18 technologies on this site, covering package cdn, analytics, advertising, and CDN. The stack includes iubenda, Amazon SES, and cdnjs.
For context, it's more locked down than the typical Hacker News launch.
