We need support in WILDFLY

We need support in WILDFLY at enterprise level for wildfly10.1.0.Final....

Im newly to wildfly

Here i have some doubts.

1) can we download software from http://wildfly.org/downloads/ .. and use it for production (or) we have to pay and then will u send some anther link to download wilfly ?

2) if we download for free and use it .. if we ran into any issues .. will u support for free or we have to pay then for ur support..?

Thanks in Advance.
