Whilst any WinGate license can be used to develop on (Free, Standard, Professional or Enterprise), the various licenses themselves have restrictions on their functionality. This may limit what you can do as some modules might not be loaded or have different functionality depending on the WinGate license used. Please ensure you have the correct WinGate license so it supports the features you require for your plugin development. More information on the various WinGate licenses can be found on our website.
