Open, Simple, Familiar

Combining the past and the present to build the future of mainframe

Zowe is an integrated and extensible open source framework for z/OS. Zowe, like Mac OS or Windows, comes with a set of APIs and OS capabilities that applications build on and also includes some applications out of the box.


Zowe offers modern interfaces to interact with z/OS and allows you to work with z/OS in a way that is similar to what you experience on cloud platforms today. You can use these interfaces as delivered or through plug-ins and extensions that are created by clients or third-party vendors.

Zowe is composed of several components, each improving the learning ability, accessibility, and possibility of mainframe development.
