Why You're Here
Rally's migration tool only handles Rally's apps.
Broadcom shipped one-click migration tools in Q2 2026. They convert the native widgets Rally ships with the platform: Custom List, Progress, Query Tile, Bar Chart. That part is solved.
Anything your team built, every Custom HTML widget, every App SDK app with custom logic, gets flagged in the error log:
"Custom HTML contains JavaScript and cannot be automatically converted. A placeholder widget was created."
That's not a bug in Rally's tool. It's the scope. Custom-built apps are still a manual rebuild, and the deadline is October 31, 2026.
Why It Works
Trained on the largest combined catalog of Rally apps in the world.
Generic React knowledge produces code that compiles. It doesn't produce code that knows Rally's WSAPI has opinions about hierarchical data, that scope context lives in App.getContext(), or that the legacy SDK papers over a decade of API quirks.
The CustomAgile GitHub organization has 474+ public repositories accumulated over more than a decade: simple query tiles, full PI planning dashboards, everything in between. Add every open-source Rally app we could track down, and you have the largest combined catalog of Rally apps in the world. WidgetAI was trained on all of it.
