Zowe version 2.7.0 is now available. You can download the installers for this release from the Download page. To learn what's new in this release, see the Release notes.

Zowe, the integrated and extensible open source framework for z/OS, combines the past and present to build the future of mainframes. Like Mac OS, Windows, and others, Zowe comes with a core set of applications out of the box in combination with the APIs and OS capabilities future applications will depend on.

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 projects

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

Zowe Application Framework

Zowe CLI

Long Term Support Core

Provides a command-line interface that lets you interact with the mainframe remotely and use common tools such as Integrated Development Environments (IDEs), shell commands, bash scripts, and build tools for mainframe development. It provides a set of utilities and services for application developers that want to become efficient in supporting and building z/OS applications quickly. The CLI provides a core set of commands for working with data sets, USS, JES, as well as issuing TSO and console commands.
