## What it is
A command line tool that brings the browser compatibility data of caniuse.com to the terminal. It lets developers quickly look up which browsers support a given web feature without leaving the command line.

## Use cases
- check browser support for websockets from the terminal
- look up which browsers support HTML5 input types
- quickly query caniuse data without opening a browser
- check feature compatibility percentages across browsers
- find out if a CSS or JS API feature is safe to use
- search caniuse features by keyword in the shell

## When to choose
- you live in the terminal and want fast caniuse lookups
- you need quick browser support checks while coding
- you want colored, concise compatibility output without a browser

## When to avoid
- you need the interactive UI, charts, or detailed notes of caniuse.com
- you need programmatic access to the data (use the caniuse-db dataset instead)
- you need up-to-the-minute data beyond what the bundled dataset provides
