The Eclipse Public License ( EPL ) is a free software license that grants the right to use, modify and distribute software freely, privately or commercially, under certain conditions. It is a slightly modified version and the successor to the Common Public License ( CPL ). The EPL is the standard license for projects led by the Eclipse Foundation .

The Eclipse Foundation published the current version 2.0 of the EPL in August 2017, which is intended to replace the original version of the EPL in the Foundation's projects. The Open Source Initiative and the Free Software Foundation recognize the EPL in both versions, even though only EPL 2.0 is compatible with the GNU General Public License (GPL) as an extension .


In both versions, the EPL enables commercial and private use, modification, distribution and sublicensing of the software. The prerequisite for this is that the license must be delivered with the software, the source code of the software has been published and the copyright of the original authors is retained. In addition, the original source code must be delivered.

Should the software licensed under the EPL become part of commercial software, the original authors must be defended and compensated by the provider of the commercial software in the event of damage or legal proceedings arising as a result. Thus, any guarantee for the software published under the EPL is excluded.

EPL 2.0

In May 2013, the Eclipse Foundation began a discussion on the revision of the EPL and published the EPL 2.0 on August 24, 2017. In this new version, changes were made to make the license easier to use internationally, to offer the possibility to use the EPL with the To make GPL compatible, also to license software written in scripting languages and to specify some of the terms more precisely and to standardize them with other licenses.
