Developer and Tester license is Free or not? if not, Is it different with production license?
Dear Customer,
Could you please clarify your question? Is it related to NWDS? (based on the selected primary tag)
If yes my answer is that you don't need any license to NWDS directly. Please check the following SAP note:
607141 - License key request for SAP J2EE Engine
Best regards,
Szabolcs
