Payara Server is an open-source application server derived from GlassFish Server Open Source Edition. It was created in 2014[1] by C2B2 Consulting as a drop in replacement for GlassFish after Oracle announced it was discontinuing commercial support for GlassFish. By comparison to GlassFish, Payara Server is released more frequently on a quarterly basis with added bug fixes, patches and enhancements. Since April 2016 Payara Server is sponsored by Payara Services Ltd who are responsible for ongoing development and coordinating community contributions.


Payara Server has been developed in 2014 as a fork and drop in replacement for GlassFish Server Open Source Edition. It was released in October 2014 in response to Oracle’s announcement to end commercial support for GlassFish.[2] Commercial support for Payara Server users is currently provided by Payara Services Ltd.

Payara Server is derived from the upstream GlassFish source tree with Payara’s own enhancements and fixes. Development of Payara Server is independent from Oracle’s development of GlassFish, and Payara Server releases are always based on the most recent version of GlassFish.

Payara Server is dual licensed under both the Common Development and Distribution License (CDDL) Version 1.1 or CDDL and GPL v2 + the Classpath exception.


The Payara Server project is hosted on GitHub,[3] allowing the community access to view and edit the source code. Payara encourages the community to contribute through raising bugs, suggesting new features and enhancements on GitHub.

Payara uses the Fork and Pull model. This means that if community members want to make any changes, they need to fork the Payara project and make their changes in their own repository. They will then need to create a pull request back into the Payara project's master branch to merge the changes into the main project.

Payara Services Ltd commercial support subscriptions also fund development and engineering effort of the Payara Server open source project.
