What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A Ruby gem for detecting browsers, bots, devices, and platforms from user agent strings. It includes ActionController integration for Rails applications.
Use cases
- detect browser type and version from user agent in Ruby
- identify bots and search engine crawlers in a Rails app
- detect mobile devices and tablets from request headers
- serve different content based on browser or platform
- detect iOS or Android version from user agent
- block or flag bot traffic in a web application
When to choose
- you need user agent parsing in Ruby or Rails
- you want device, platform, and bot detection in one gem
- you need ActionController integration for request-based detection
When to avoid
- you need client-side feature detection rather than user agent sniffing
- your project is not in Ruby
- you need high-throughput log analysis of user agents at scale
