Payara Server – Robust, Reliable, Supported

Payara Server is an open source application server derived from GlassFish, with an option of 24/7 Production and Migration & Project Support. It is a drop-in replacement for GlassFish Server Open Source Edition, with the peace of mind of quarterly releases containing enhancements, bug fixes and patches - see the Data Sheet here.

Payara Server is a perfect solution for companies currently using GlassFish, struggling with lack of support from Oracle and infrequent, low-quality application server releases. To see exactly how Payara Server is better than GlassFish, check out our comparison table.

Payara Server is also a great product for any organisation running Java EE applications, looking for a robust, reliable and supported platform.

There is also Payara Micro, which enables you to run war files from the command line without any application server installation. Payara Micro is perfect for microservices and cloud environments, it is small, < 70MB in size and incredibly simple to use. With its automatic and elastic clustering, Payara Micro is designed for running Java EE applications in a modern containerized/virtualized infrastructure.  Payara Micro also comes with a Java API so it can be embedded and launched from your own Java applications.

Both Payara Server and Payara Micro are compatible with the Eclipse MicroProfile.
