## What it is
UME is an in-app debug kits platform for Flutter applications, providing 13 built-in plugin kits for UI inspection, device info, and performance monitoring. Developers can also create and integrate custom plugin kits into the platform.

## Use cases
- inspect Flutter widget trees inside a running app
- monitor app performance on device during development
- view device info from within a Flutter app
- build custom in-app debugging tools for Flutter
- debug Flutter apps without connecting to an external IDE

## When to choose
- you develop Flutter apps and want on-device debugging tools
- you need widget inspection or performance stats inside the running app
- you want an extensible debug kit platform with custom plugins

## When to avoid
- you only need standard IDE-based Flutter DevTools
- your project is not built with Flutter or Dart
- you need a production monitoring/APM solution rather than a dev tool

## Facets
- artifact type: library
- maturity: active
- function: developer-tools, testing, monitoring, plugin-system
- domain: developer-tools, mobile-development, cross-platform
- platform: windows
- tags: flutter, in-app-debugging, devtools, debug-kits, dart, widget-inspector, ios, android, web, macos, linux
