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

Fan is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on August 10, 2026. The site is served through Cloudflare, with a domain registered 5 months before launch. The crawl picked up 3 technologies on this site, covering CDN, developer tools, and web fonts. The stack includes Cloudflare, Google Fonts, and Vite.
