# What device.type am I using?

##

{UAParser.js} detect Browser, Engine, OS, CPU, and Device type/model from User-Agent data with relatively small footprint (~17KB minified, ~6KB gzipped) that can be used either in browser (client-side) or node.js (server-side).

Now, detecting browser is as simple as ua.getBrowser()

USER-AGENT PLAYGROUND

{UAParser.js} abstracts away the hassle of User-Agent detection by turning them into a set of simple & meaningful data. As an example, this is what we get from your browser's User-Agent information:

{UAParser.js} reads this as:

Browser
Engine
OS
Type
Model
CPU

###
Extract Only What's Valuable

It's widely known that User-Agent string as of today is a mess. On the other hand, there is no reliable way to identify browser. {UAParser.js} fills this gap by filtering the noise away and extracts only the most relevant data available: Browser, Engine, OS, CPU, and Device.

###
Relatively Small Footprint

Started from JavaScript approach, {UAParser.js} is optimized to be used with browser. While it covers a vast range of detection, the size always kept to be as light as possible. For extra cache performance, {UAParser.js} also available in popular CDN services (jsDelivr/CDNJS).

###
