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 23 April 2026; the live site may have changed since.

SIFU is partway there. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on April 23, 2026. The site is hosted on Vercel, with a domain registered 2 days before launch. The crawl picked up 10 technologies on this site, covering analytics, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 10,671 other launches.
