A JavaScript library for user-agent analysis and browser detection that identifies browser, engine, OS, device, GPU, network, and other client details. It also supports feature detection and generates a composite browser fingerprint.
Use cases
- parse user-agent strings to detect browser and version
- detect device type and OS for responsive content adaptation
- check whether the client is a bot or webview
- collect browser fingerprint data for analytics
- detect support for fonts, WebGL, or NFC features
- log client environment details for debugging
When to choose
- you need lightweight browser/device detection in frontend or Node.js
- you want fingerprinting and feature detection beyond simple UA parsing
- you need broad browser coverage with ongoing data updates
When to avoid
- you need server-side log-scale UA parsing at very high throughput
- you rely on user-agent strings for security decisions (spoofable)
- you need a full commercial-grade device intelligence database
