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 30 April 2026; the live site may have changed since.
Quadrant is largely in shape, with complete legal pages and well-configured email security. What needs work: missing Permissions-Policy and Content-Security-Policy, no robots.txt or sitemap, and tracking cookies set before any opt-in.
Launched on Product Hunt on April 30, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 10 months before launch. The crawl picked up 12 technologies on this site, covering analytics, security, auth, and CDN. The stack includes Clerk, Next.js, and React.
For context, it's running the same core stack as 10,671 other launches and tighter on security headers than most Product Hunt launches.
