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 29 July 2026; the live site may have changed since.

知芽 · Notebook Skill is early-stage. Visible gaps: missing several security headers, no robots.txt or sitemap, and no email security records.

We've detected 8 technologies on this site, covering directory, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.
