Yep, just use this

request.env["HTTP_USER_AGENT"]
#or
request.user_agent

I'm not sure that we can call that a "solid way" :p – Nicolas Guillaume Oct 04 '11 at 16:17

What about using a simple gem?

If I remember well, I used this one last time.

gem install user-agent

The same one on GitHub

I think that this is a good way to do it...

LOL there's a gem for that. – f0ster Jul 30 '13 at 20:31
That's a quite old gem which [does not even include Windows 8](https://github.com/tj/user-agent/blob/1.0.0/lib/user-agent/agent.rb#L121), and it has only one single release on RubyGems. I would suggest `useragent` with operating system support up to [Windows 10](https://github.com/gshutler/useragent/blob/v0.16.7/lib/user_agent/operating_systems.rb#L6). – Franklin Yu Aug 28 '16 at 20:08
