## What it is
A deprecated React component library providing runtime developer tools for MobX-powered React applications. It visualizes component rendering behavior, render counts, and render timings, and logs MobX actions and reactions to the browser console.

## Use cases
- debug why my React components are re-rendering with MobX
- profile render times of MobX React components
- trace MobX actions and reactions in the browser console
- highlight components that take too long to render
- inspect data dependencies of reactive React components

## When to choose
- maintaining a legacy app on mobx-react@5 or earlier that needs runtime render diagnostics

## When to avoid
- starting a new project - the package is deprecated
- using mobx-react@6 or higher, where the devtools are no longer needed
- you want the maintained browser plugin (mobx-devtools) instead

## Facets
- artifact type: library
- maturity: abandoned
- function: monitoring, developer-tools, ui-components
- domain: frontend, web-development, developer-tools
- platform: browser
- tags: mobx, react, devtools, deprecated, rendering-performance, state-management-debugging, debugging, nodejs, javascript
