Your IBM i system has been running your business for decades without missing a beat. But then a new hire sits down at their workstation for the first time, looks at the green screen staring back at them, and asks: “Is this what I’ll be working on every day?” That moment might make even you pause and wonder — is the system failing?
The backbone of your mission-critical enterprise operations isn’t broken. Its interface, however, belongs to a different era. The gap between what your IBM i does and how it looks to the people using it is becoming harder to ignore. Traditional 5250 terminals or green screens are increasingly slowing down users, extending training cycles, and making it harder to attract new talent.
With expectations around user experience changing fundamentally, business leaders are left wondering: how to deliver modern digital experience without disrupting the systems that already work?
Why Traditional IBM i Modernization Approaches Often Fall Short
When green screen limitations start affecting, the instinct is to modernize. But for most IBM i leaders, the need to modernize isn’t a question of if — it’s a question of how. The path forward is rarely straightforward.
When organizations begin evaluating their options, they quickly run into a familiar problem: every path forward seems to introduce new risks, operational challenges, or costs. Every conventional modernization approach comes with a trade-off between progress and stability, making leaders pause and for good reason.
- UI Development: Although it may sound like a middle ground, custom UI development rarely delivers on that promise. Building bespoke, flexible interfaces from scratch leads to high development costs, long timelines, an ongoing maintenance burden that compounds over time, and reliance on the shrinking RPG talent pool.
- System Rewrite: Despite seeming to be the cleanest solution on paper, full system rewrites are often expensive, multi-year undertakings with high failure rates and uncertain ROI. Additionally, a rewrite risks losing decades of business logic embedded in your RPG and COBOL code — something that your team may not even fully document because it has simply always worked.
- Replatforming: Moving workloads to a new platform promises modernization. However, it introduces extended downtime risks, operational disruption, and a transition period where both old and new systems need to be maintained simultaneously. That’s what makes replatforming a risk most IBM i businesses aren’t willing to take.
- Middleware Layers: Designed to bridge multigenerational and modern systems, middleware adds yet another variable into an already complex environment. Every additional layer introduces new failure points, latency, and integration debt that your team will be managing for years.
That’s exactly where Green2Glass comes in—helping enterprises modernize their IBM i green screens without disrupting what already works.
How Green2Glass Eliminates the Modernization Trade-Off
Green2Glass is an IBM i-native, low-code modernization toolkit that automatically transforms aging green screens into intuitive, browser-based interfaces—without touching your core logic, security models, or workflows.
Instead of replacing what already works, Green2Glass gives your IBM i a modern, responsive face that today’s workforce expects. Your applications continue to behave exactly as they always have—only now they are easier to use, faster to navigate, and accessible across modern devices.
Key Green2Glass Features at a Glance
Green2Glass is built around a focused set of capabilities designed to deliver modernization that is fast, flexible, and fully compatible with your existing IBM i environment. Here is what it brings to the table:
- AI Assistant: A built-in AI model that uses intelligent context analysis for delivering accurate, IBM i data-backed, plain English-based answers to user queries instantly.
- Button Panel: A control unit that replaces command-line green screen function keys with clickable, user-defined buttons — so users can trigger actions with a click instead of manually entering keyboard commands.
- Cross-Browser Compatibility: A feature that enables interfaces to run across all major web browsers — including Chrome, Firefox, and Internet Explorer 11 — without additional configuration.
- Data App Builder: An easy-to-use, visual interface that helps you choose a modern theme from an array of preset templates and design custom application screens without writing a single line of code.
- Drag-and-Drop Controls: toolbox that lets you align interfaces with workflows by rearranging buttons, fields, inputs, panels, and subfiles without coding.
- Enterprise-Ready Architecture: A capability that enables you to enhance user experiences of on-premises, hybrid, or cloud-based IBM i systems without any additional middleware.
- Role-Based Menus and Navigation: A centralized space that allows administrators to manage developer and user navigation, monitor logged-in people, and maintain themes.
- Screen Transformation Engine: An integrated functionality that automatically migrates COBOL and RPG-based green screens into web, mobile, browser-responsive GUIs — all while preserving existing workflows and business logic.
- Theme Designer: A dashboard that allows you to personalize interfaces with diverse fonts, colors, and branding styles. Additionally, it offers a real-time visual preview to ensure the final result matches your vision, making UI personalization accurate, easy, and fast.
- Universal Settings: Centralized settings that allow you to apply consistent design rules and configurations across multiple application screens at once, saving time and ensuring a uniform user experience.
Who Green2Glass Is Built For
Green2Glass was designed with a specific kind of organization in mind — one that has built its operations on IBM i but is under increasing pressure to evolve the experience around it. More specifically, Green2Glass is ideal for:
- Organizations running their business-critical operations on IBM i with RPG/COBOL applications they can’t afford to rewrite — but can’t afford to leave as-is.
- IT teams managing IBM i maintenance operations while being asked to modernize faster — within limited costs, resources, and timelines.
- Distribution, insurance, logistics, manufacturing, and retail companies relying on IBM i for mission-critical operations — where reliability, performance, and continuity are non-negotiable.
- Companies that have evaluated other modernization paths and found them too slow, risky, or costly.
In short, Green2Glass is built for IBM i teams and enterprises that don’t want to choose between stability and progress — they want both.
How Green2Glass Adds Value to Your Business
By removing the traditional modernization barriers, Green2Glass not only improves the interface but also changes what your organization can do with it. Here’s how it delivers measurable value across your business:
- Accelerated Modernization: By cutting modernization time and costs by up to 70% compared to traditional approaches, Green2Glass enables your team to launch a modern, browser-based UI in days instead of months — while maintaining operational continuity.

Parting Thoughts
Over the decades spent working alongside IBM i enterprises, we saw how teams were caught between sustaining existing systems and transforming green screen experiences. The modernization options available often forced them to sacrifice either integrity or innovation. So, they waited. And during this time, user frustration grew, the RPG talent pipeline shrunk, and the gap between what their IBM i could do and what their business needed widened.
That’s where the idea for Green2Glass took shape.
Built by IBM i Champions who understand the platform, the restraints, and the stakes involved in every decision, Green2Glass offers a more practical path forward. Rather than discarding decades of proven business logic and code, it preserves the stability of IBM i systems while evolving the experience around them.
