ua-device is a JavaScript library by Baidu's FEX team that parses User-Agent strings to extract browser, engine, OS, and hardware device information. It specializes in accurately identifying Chinese mobile device manufacturers and models where generic UA parsers fail.

Use cases

  • parse user-agent strings to detect device manufacturer and model
  • identify mobile device brands from UA in Chinese web traffic
  • get browser, engine, and OS info from user agents
  • aggregate device stats without splitting same phone across UA variants
  • detect device type (mobile/pc) server-side in Node.js

When to choose

  • your traffic includes many Chinese Android devices with non-standard UAs
  • you need device manufacturer/model recognition rates higher than generic UA parsers
  • you want a lightweight Node.js/browser library for UA parsing

When to avoid

  • you need actively developed features or frequent updates
  • your users are mostly outside China and standard parsers like ua-parser-js suffice
  • you need TypeScript types or modern ESM support
