Izzi Software Bridges Mainframe Skills Gap with VS Code Debugger

MINNEAPOLIS, MN – August 03, 2026 – In a significant move to bridge the gap between legacy systems and modern development practices, Izzi Software has launched its flagship mainframe debugging tool, Z/XDC, as an extension for Visual Studio Code (VS Code). The announcement signals a strategic effort to address one of the most persistent challenges in enterprise IT: the critical shortage of skilled mainframe professionals.

Izzi Software, which owns the 40-year-old mainframe solutions provider ColeSoft, is betting that by integrating its powerful debugger into the world's most popular code editor, it can demystify mainframe development for a new generation. “We’re very excited to release our Z/XDC extension for VS Code,” said Jennifer Nelson, CEO of Izzi Software, in a statement. “Izzi Software is making mainframe development more accessible to the new generation of coders who can now leverage an expansive suite of features right in the IDE they use every day.”

The move is more than a simple product update; it’s a direct response to a slow-burning crisis. Mainframes remain the digital bedrock for the global economy, processing the majority of credit card transactions and powering core systems for 92 of the top 100 global banks. Yet, the workforce that maintains them is rapidly approaching retirement, creating a talent vacuum that threatens to disrupt these critical operations.

The Mainframe's Enduring Dilemma: Power vs. People

The term “looming skills gap” has been an industry refrain for two decades, but recent data underscores its escalating urgency. Industry reports consistently show that the average mainframe specialist is over 50 years old, with an estimated 60% of this highly experienced workforce nearing retirement. This impending “brain drain” represents a catastrophic loss of institutional knowledge that cannot be easily replaced.

Despite this, demand for mainframe talent is surging. A recent survey found that 91% of organizations plan to hire mainframe developers or administrators in the next two years. The challenge is not just finding programmers fluent in legacy languages like COBOL; it’s sourcing talent with modern skills in AI, cloud integration, and cybersecurity within a mainframe context. According to one study, 70% of organizations struggle specifically with finding the skills needed for mainframe modernization projects.

This disconnect between supply and demand has tangible economic consequences. Research firm IDC has projected that IT skills shortages across all sectors could result in over $5.5 trillion in global losses by 2026, with the highly specialized and mission-critical mainframe sector being particularly vulnerable. “You can’t run the world’s financial systems on hope,” commented one independent industry analyst. “Without a clear pipeline of new talent, organizations are facing significant operational risk. This isn’t a hypothetical problem; it’s a strategic imperative.”

A Modern Bridge to a Legacy World

Izzi Software's solution attacks the problem at its source: the developer experience. For decades, mainframe development has been associated with text-based “green screen” interfaces that are alien to younger developers raised on graphically rich, intuitive Integrated Development Environments (IDEs) like VS Code. By bringing its Z/XDC interactive debugger into this familiar environment, the company drastically lowers the barrier to entry.

The Z/XDC extension allows developers to interactively debug mainframe software in real-time directly from their preferred editor. This eliminates the steep learning curve associated with traditional mainframe tooling and allows new hires to become productive faster. It transforms debugging from a cryptic, command-line-driven process into a visual, interactive experience that aligns with modern DevOps workflows.

“The cultural barrier has always been as significant as the technical one,” noted a senior enterprise architect at a major financial institution. “You can’t expect a 22-year-old developer to be productive, let alone happy, working on a 40-year-old interface. Bringing the work to their preferred environment is a game-changer. It makes a career in mainframes a viable and even attractive path, rather than a reluctant necessity.” This sentiment is supported by broader industry findings, with 95% of IT leaders agreeing that providing modern development tools is a key strategy for attracting and retaining talent and closing the skills gap.

The Strategy Behind the Software

This launch is not an isolated event but a calculated move in a larger business strategy. Izzi Software is owned by Big Band Software, a firm specializing in acquiring and growing profitable B2B software-as-a-service (SaaS) businesses. This backing provides the financial muscle and strategic vision to modernize legacy assets for long-term growth. The 2025 acquisition of CNX Corp, another player in the enterprise software space, further illustrates a pattern of consolidation and modernization.

The playbook is clear: identify mission-critical software with a stable, paying customer base, and then invest in modernizing the user experience and integration capabilities to expand its market. By making Z/XDC accessible to the millions of VS Code users, Izzi isn't just serving its existing customers; it's creating a new on-ramp for a vast pool of untapped talent.

“Big Band’s model is a smart one for the current enterprise landscape,” observed a technology M&A analyst. “They aren’t trying to reinvent the wheel. They find indispensable software that runs core business functions, inject capital to smooth over the roughest user-experience edges, and effectively extend the product’s life and market reach. It’s a low-risk, high-reward strategy that capitalizes on the inertia and criticality of legacy systems.” This approach ensures that vital tools like Z/XDC don't fade into obsolescence along with their original user base, but instead evolve to meet new demands.

By integrating a four-decade-old debugging powerhouse with today's top development environment, Izzi Software is doing more than launching a product. It's building a crucial piece of infrastructure to ensure the stability, security, and continued evolution of the world's most important computer systems for the next generation.
