Features

  • Direct PostgreSQL Connectivity Connect Unreal Engine directly to any PostgreSQL server (local or remote).

  • SSL Support Optional SSL connection with selectable SSL modes and optional root certificate use.

  • OS Support Currently supports Windows only. (Tested on Windows 10 with UE5.2)

  • Query Execution Run SQL commands, retrieve results, and map rows/columns easily.

  • Blueprint-Friendly All major operations exposed as simple Blueprint nodes.

  • CSV + Structured Results Query results can be returned both as CSV rows and structured maps.

Available Functions
