{"database":{"type":"mysql","mysql_host":"127.0.0.1","mysql_port":3306,"mysql_user":"aisbf","mysql_password":"change-me","mysql_database":"aisbf"}}

During the current testing period, hosted Pro is available as unlimited access for €6/month or €60/year; subscribing helps fund continued AISBF development and infrastructure while this one-human project is still demo-stage.
