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.

API Mediation Layer

Provides a gateway that acts as a reverse proxy for z/OS services, together with a catalog of REST APIs and a dynamic discovery capability. Base Zowe provides core services for working with MVS Data Sets, JES, as well as working with z/OSMF REST APIs. The API Mediation Layer also provides a framework for Single Sign On (SSO).

Zowe CLI

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.

Zowe Workflow wiZard (Incubator)

The Workflow wiZard delivers a workflow builder which simplifies the creation of z/OSMF workflows. These workflows can be very helpful for automating workloads or guiding users through a set of ordered steps to complete a task, but they can also be complex and challenging to create. The workflow builder was created to address these challenges.
