## What it is
A browser developer tool extension for inspecting the rendering performance of React components, based on measures collected via the window.performance API. It also provides an npm module to log performance measures to the console.

## Use cases
- profile react component render performance
- find which react components are slow to load
- identify components that need shouldComponentUpdate
- inspect what is blocking react renders
- log react performance measures to console

## When to choose
- you are debugging render performance of a React app in Chrome
- you want a visual table of component load and update times

## When to avoid
- you need actively maintained tooling for modern React (project is looking for maintainers)
- you use frameworks other than React
- you need production performance monitoring rather than local debugging

## Facets
- artifact type: plugin
- maturity: maintenance
- function: monitoring, benchmarking, developer-tools
- domain: frontend, web-development, performance, developer-tools
- platform: browser, browser-extension
- tags: react, profiling, chrome-extension, devtools, performance-monitoring, nodejs
