Infinite UI is dynamic runtime modernization for Infinite i. It captures your live green screens into a versioned JSON screen model and renders them as modern, composable web experiences — automatically, with no rewrite and no screen-by-screen recoding.
Most modernization tools stop at colors, fonts, and field repositioning. Infinite UI goes further: it understands 5250 screen state — subfiles, function keys, cursor, field attributes, and job/session semantics — and turns it into modern, composable web apps that preserve the interaction fidelity of your host application while adding everything the web makes possible.
Every screen is classified — list, form, subfile, workspace — and rendered from the JSON model as a modern grid, form, or workspace. Page sizes and record formats from the host are preserved.
First-class, schema-defined agents for titles, menus, subfiles, command bars, buttons, date/time, combo boxes, and popups. AI suggests mappings; humans approve before production.
Choose templates like List & Detail or Form Workspace and tune behavior with admin rules — no code. Versioned screen packages promote from dev to test to prod.
Bring Power BI dashboards, SharePoint documents, Teams channels, and Google Sheets right beside the host screen — with CSP and sandbox policy controls.
Attach WebSocket / SSE streams, job logs, and audit feeds, and compose guided multi-screen task flows with checklists, approvals, and validation.
SSO and RBAC, a customer admin console separate from Infinite admin, versioned packages, dev/test/prod promotion, and a full audit stream on every session.
The same IBM i application, rendered by Infinite UI as a modern workspace — with the host option path preserved on every screen. Representative transformations:
Infinite UI turns live Infinite i screens into modern, composable web experiences without rewriting the application. Tell us about your green screens and we'll show you what they look like as web apps.
