🚀 New Feature: Langfuse-managed Read-Only Dashboards and Widgets

A new feature has been added to Langfuse that introduces support for Langfuse-managed (read-only) dashboards and widgets. This enables users to access pre-built, global dashboards and widgets maintained by Langfuse, while still allowing project-specific customization and duplication.

Highlights

• Read-Only Dashboards & Widgets:
  • Langfuse now provides managed dashboards and widgets that are read-only and available globally across projects.
  • These are distinguished from project-owned dashboards/widgets by a new owner field (PROJECT or LANGFUSE).
• Widget & Dashboard Cloning:
  • Users can duplicate ("clone") Langfuse-managed widgets and dashboards into their own projects for further customization.
  • New UI actions and API endpoints support this workflow.
• UI Improvements:
  • Ownership is now clearly displayed in dashboard and widget tables.
  • Edit/delete actions are restricted to project-owned items; clone actions are available for Langfuse-managed items.
  • Improved navigation and feedback when working with dashboards and widgets.
• API & Backend:
  • New copyToProject mutation for widgets.
  • Dashboard and widget services and schemas updated to support ownership and duplication logic.

Migration & Compatibility

• No breaking changes for existing project dashboards or widgets.
• Existing dashboards/widgets are now marked as PROJECT-owned; new global items are marked as LANGFUSE-owned.

Developer Notes

• See PR #6873 for full technical details and implementation notes.
• Main files changed: DashboardService.ts, types.ts, dashboard/widget UI components, and API router for dashboard widgets.
