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 April 2026; the live site may have changed since.

MCP Playground Online is largely in shape, with a thorough launch checklist and clean crawl signals. What needs work: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on PeerPush on April 9, 2026. The site is hosted on Vercel, with a domain registered 4 months before launch. The crawl picked up 14 technologies on this site, covering analytics, advertising, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 10,661 other launches and tighter on security headers than most PeerPush launches.
