Usually, spiders must disguise themselves with plenty of User-Agents, for some servers are smart. The gem useragents can give you that!

It has frequently-used browsers such as Chrome, Firefox, Internet Explorer, Safari, Opera and so on, with frequently-used versions.

The usage is simple, just install the gem at first, then require 'useragents, and at last, UserAgents.rand() works for you!

Enjoy it!

gem install useragents

require 'useragents'

# Generate a random useragent for you
UserAgents.rand()
