Commitment to Open Source

The Globus Alliance is committed to maintaining a liberal, open source license. The Globus Toolkit Public License (GTPL) allows software to be used by anyone and for any purpose, without restriction. We believe that this is the best way to ensure that Grid technologies gain wide spread acceptance and benefit from a large developer community.
