Speed is paramount in today’s digital economy – yet many mainframe shops slam the brakes on their DevOps journey by continuing to use outdated development tooling. Using green-screen technology forces developers to perform lengthy, error prone tasks that involve context switching. This costs productivity and time-to-market. When speed to market is key to gaining competitive advantage, businesses need to be agile and cost-efficient, two goals that are contrary to the continued use of disparate, green-screen development tools.

Other vendors might tout powerful development environments, but none are truly versatile and extensive in their ability to handle all aspects of z/OS development – from COBOL to REXX and everything in between. IBM’s application delivery tools have foundational, integrated capabilities that help facilitate your company’s Digital Transformation. If a business wants to win and get ahead, a comprehensive, proven Integrated Development Environment (IDE) serves as the cornerstone of development’s daily activities.


 IBM Developer for z Systems (IDz) is the only IDE that was developed specifically to help customers modernize their decades old applications, and not just as a “me too” product to take market share. IDz, with automated creation of web services for COBOL and PL/I, helps accelerate your entry into the Application Program Interface (API) Economy. It sets the standard for other major software vendor’s IDEs as the industry’s most capable, feature-rich IDE. All the other vendors play catch-up to the cutting edge technology that’s packed in to every release of IDz.

IDz is the industry’s most broadly adopted IDE, with more active licenses than any other modern mainframe IDE on the market. It is an integral part of the most broad integration platform to date, z/OS Explorer Aqua, which consists of 17 products that are released monthly. These releases use an automated delivery platform to integrate and test these products so they work together, which simplifies the installation and deployment process. It provides the most customizable end-user experience. IDz also includes the IBM z/OS Debugger, which in itself is an industry leader.  Others require separate debugger licensing.

With the ability to create custom development “perspectives”, set custom preferences, generate shop-specific code templates, govern code by custom rule-sets, and create your own context-sensitive menus to integrate with other IBM and non-IBM tools, IDz can custom-tailor the end-user experience endlessly. This results in an equally rich experience for the hardcore mainframe developer, development lead, or architect.

IDz bridges the gap between early-tenure developers and veteran mainframe programmers. With an included ISPF editor to ease onboarding for veteran programmers and provide access to home-grown ISPF panels while new solutions are being delivered, IDz allows early-tenure programmers to onboard quickly and efficiently with access to tooling that brings enterprise-level code bases within reach for understanding. This gives everyone across the development teams a level playing field and ground on which to move forward with complex issues and projects.


IDz is available via a wide range of licensing options to meet your needs.  There are several user-based licensing options and capacity-based licensing as the cornerstone of IBM Application Delivery Foundation for z Systems, which is a complete, integrated set of tools to create and maintain z/OS applications. To learn more, check out the IDz trial, videos, and blogs available on mainframeDevOps.

The mainframe has been continuously optimized like a Ferrari racecar, yet mainframe development practices have not always kept up. Only IBM’s Developer for z System offers the required depth and breadth of capability and integration that mainframe developers need to fuel a fast DevOps pipeline to drive your company’s Digital Transformation.
