Wildcard Subdomain Architecture Without VPS or cPanel

Understand how DNS wildcard records (*.myfa.page) and Next.js Edge Middleware route unlimited tenant subdomains on a $0 serverless budget.

Architectural Key Takeaways

An A record for @ (76.76.21.21) and a CNAME record for * (cname.vercel-dns.com) route every subdomain to Vercel's Anycast Edge network.
Next.js Edge Middleware inspects the incoming Host header in sub-millisecond time without spinning up a Linux container.
Internal URL rewriting maps hacker.myfa.page/top-hack-now to /sites/hacker/top-hack-now while preserving the clean browser address bar.
Reference Implementation Snippet
export function middleware(request) {
  const host = (request.headers.get("host") || "").split(":")[0];
  if (host.endsWith(".myfa.page")) {
    const sub = host.replace(".myfa.page", "");
    const url = request.nextUrl.clone();
    url.pathname = `/sites/${sub}${url.pathname === "/" ? "" : url.pathname}`;
    return NextResponse.rewrite(url);
  }
  return NextResponse.next();
}
Interactive Knowledge Verification
Why does MyfaPost use NextResponse.rewrite() instead of NextResponse.redirect() for tenant subdomains?
