Platform.js is a JavaScript library that detects the browser, engine, OS, and device from the user agent, working across browsers and Node.js. It can also parse arbitrary UA strings, though it is intended for informational purposes rather than replacing feature detection.

Use cases

• detect browser name and version in javascript
• parse user agent strings
• identify operating system and device from ua
• show browser info on a support page
• get os and layout engine in node.js

When to choose

• you need lightweight browser/OS detection from a user agent string
• you must support legacy environments like old Node or PhantomJS
• you want a simple informational platform description string

When to avoid

• you need actively maintained detection for the latest browsers
• you want feature detection instead of user-agent sniffing
• the repo is archived and read-only since April 2024
