Automated Green Screen Modernization

Instant Web GUI Transformation

Presto eliminates the complexity of manual recoding by instantly converting your existing green screens into a modern web GUI.

  • Global Transformation: Presto automatically recognizes and transforms standard 5250 elements—such as menu screens, subfiles, and function keys—into intuitive web components.
  • Zero Client Installation: Deploy your modernized applications directly from the IBM i server. Users access the interface via a standard browser, removing the maintenance burden of client-side software.
  • Immediate Accessibility: Your applications become accessible as secure web pages the moment Presto is installed, accelerating your UI modernization timeline.

Drag-and-Drop Customization

Visual Editor for Intuitive UI Modernization

The Presto Visual Editor empowers developers and non-technical staff to enhance the IBM i user interface without requiring deep HTML5 or CSS expertise.

  • Modern UI Elements: Enhance functionality by dragging and dropping modern controls like calendars, charts, images, and dropdown lists directly onto your screens.
  • Code-Free Integration: Add Google Maps, link to PDF documents, or integrate other web assets without writing complex code.
  • Event Handling: Use simple JavaScript events to control element behavior, such as hiding fields, auto-populating data, or triggering actions with a single click.

Scalable Application Modernization

Site-Level Settings & Global Rules

Accelerate the modernization of your IBM i applications by applying the same settings to all your web-enabled green screens.

  • Global Transformations: Define site-wide rules to handle recurring patterns. If a specific date format or function key layout appears on multiple screens, define the rule once to apply it globally.
  • Consistent Branding: Utilize custom skins to align your modern web GUI with corporate branding. Adjust color schemes, logos, and fonts centrally to ensure a unified user experience.
  • Standardized Navigation: Configure the behavior of global elements like menus and function keys to ensure consistent navigation throughout the application.

SQL Integration for Richer Interfaces

Data-Driven UI Elements

Extend the capabilities of your 5250 datastream by integrating real-time data directly into your interface.

  • Dynamic Data Population: Use SQL queries within the Visual Editor to populate dropdown lists, autocomplete fields, and charts with live Db2 data.
  • Smart Auto-Complete: Enhance data entry speed and accuracy by transforming standard input fields into auto-complete boxes driven by your database.
  • Data Export: Empower users to export subfile data directly to CSV or HTML formats for analysis in Microsoft Excel, bypassing manual copy-paste operations.

Access IBM i Anywhere

Mobile Support & Responsive Design

Presto ensures your business applications are fully responsive, enabling a seamless workflow across desktop, tablet, and mobile devices.

  • Responsive Skins: The interface automatically adjusts layout and styling based on the device’s screen size, ensuring readability and usability on iPads, iPhones, and Android devices.
  • Mobile-Specific Customization: Apply unique rules for mobile users. For example, simplify complex subfiles or enlarge buttons for touch interaction without affecting the desktop view.
  • Virtual Function Keys: Mobile users benefit from a specialized virtual keyboard that provides easy access to standard IBM i function keys (F1-F24).
Integration

Secure, Connected Web Applications

Integration and Security

Modern applications must be secure and interconnected. Presto adheres to standard web security protocols while enabling integration with third-party services.

  • API & Web Services: seamlessly integrate your screens with external APIs for functionality like shipping tracking or payment processing. Launch other web apps directly from your modernized interface.
  • Single Sign-On (SSO): Support for Kerberos and other authentication standards enables a smooth Single Sign-On experience for end users.
  • Multi-Factor Authentication (MFA): Enhance security by integrating Presto with solutions like Fresche’s Nexus to require Two-Factor Authentication (2FA) for access.
