  • A commercial production licence is not part of the free download and comes only with a subscription
  • No subscription price is published; Basic Support and Enterprise Support both require contacting sales for a quote
  • 24x7x365 coverage requires Enterprise Support; the general query SLA is one business day
  • A Customer Success Manager is a paid optional add on covering business hours only
