DEMO : A 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} will transforms it into a well-structured format:

FEATURES: WHEN LESS IS MORE

User-Agent string as of today is a mess. On the other hand, there is no reliable way to identify user details.

{UAParser.js} filters the noise away & extracts only the most meaningful data: Browser, Engine, OS, CPU, & Device in a well-structured format.

{UAParser.js} is optimized to be used within 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

No bloated framework. No transpiler required. No unnecessary boilerplate. No dependencies.

Just a good ol' ES3-compatible syntax that is able to run on relatively old browsers while also performs on most modern devices.

Licensed under an extremely permissive MIT license, {UAParser.js} is free to use & modify at no charge.
