Extension name Direct Alias & Direct Alias Pro
Developer AlterBrains.com
Reason you believe its abandoned No updates since they claim to have fixed it for Joomla 4 in Feb 2022 - Joomla 4 has had lots of development & changes since that time, also their own website (according to whois) has not been updated since 2022-05-23 - none of which gives me that warm feeling one gets from a current product or operational business/supplier.
