Cloudflare asks to subscribe to their Enteprise plan of min $5k/month to use their service for any subdomain. Even if they give a large number of DNS records (3500), if you run a free tier and your users have their own subdomain, 3500 is nothing and they won't let you increase it unless you are on Enterprise.<p>The only option would be to find some alternative that doesn't charge $5k for subdomains protection.<p>Any options?
