DejaCode is normally deployed as a Service (Software as a Service). We do have an option for local installation in which case you will need a Linux server that is connected to your internal network. Server requirements are relatively modest, but installing locally requires someone from your IT department to be the system administrator.
DejaCode is always licensed on a subscription basis – normally an annual subscription. DejaCode is available under the nexB End User License Agreement for Software as a Service (EULA) or under the nexB Software Subscription License Agreement (SSLA).
