## What it is
A PHP user agent parser that identifies browsers, operating systems, devices, robots, and accept languages, built on Mobile Detect with added desktop support. It integrates with Laravel via a service provider and facade.

## Use cases
- detect mobile devices from user agent strings in PHP
- parse browser and OS from a user agent header
- serve different layouts for phones and tablets
- get the visitor's preferred languages from accept-language headers
- detect bots and crawlers visiting a site
- log device and platform info for analytics in a Laravel app

## When to choose
- you need user agent parsing in a PHP or Laravel application
- you want mobile, tablet, and desktop detection in one package
- you need device names, platforms, and browser names from user agent strings

## When to avoid
- you need highly accurate, frequently updated user agent detection for modern devices
- you are not working in PHP
- you need client-side browser feature detection rather than user agent sniffing

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, nlp
- domain: web-development, developer-tools
- platform: php
- tags: user-agent-parsing, mobile-detection, laravel, browser-detection, device-detection, web-server
