UserAgentRandomizer

There exist few use cases where random HTTP User-Agent strings are required. This was the motivation for me to write this user-agent-randomizer Ruby gem. Currently it provides ca. 10.700 different HTTP User-Agent strings. You can choose a random HTTP User-Agent string from the entire pool as well as fetch a HTTP User-Agent string by category.

Every HTTP User-Agent string is assigned exactly to one of the following categories:

crawler
desktop_browser
mobile_browser
console
offline_browser
email_client
link_checker
email_collector
validator
feed_reader
library
cloud_platform
other

Installation

Add this line to your application's Gemfile:

gem 'user-agent-randomizer'

And then execute:

$ bundle

Or install it manually:

$ gem install user-agent-randomizer

Usage

The usage is pretty simple. You can fetch a random HTTP User-Agent string from the entire pool as well as one from a specified category (see the list above):

Open an IRB and require the gem first of all:

irb> require 'user_agent_randomizer'
# => true

Fetch a random HTTP User-Agent string from the entire pool:

irb> ua_all = UserAgentRandomizer::UserAgent.fetch
# => #<UserAgentRandomizer::UserAgent:0x007fe1f30a6658 @type="crawler", @string="CatchBot/1.0;  http://www.catchbot.com">

Fetch a random HTTP User-Agent for a desktop browser:

irb> ua_desktop = UserAgentRandomizer::UserAgent.fetch(type: "desktop_browser")
# => #<UserAgentRandomizer::UserAgent:0x007fe1f2282b58 @type="desktop_browser", @string="Mozilla/4.6 [en] (WinNT; I)">

Retrieve the type and the string from the objects above:

irb> puts "UA general -> type: '#{ua_all.type}', string: '#{ua_all.string}'"
# => "UA general -> type: 'crawler', string: 'CatchBot/1.0;  http://www.catchbot.com'"

irb> puts "UA desktop browser -> type: '#{ua_desktop.type}', string: '#{ua_desktop.string}'"
# => "UA desktop browser -> type: 'desktop_browser', string: 'Mozilla/4.6 [en] (WinNT; I)'"
