Podcast Agent Parser
The Podcast Agent Parser is a user agent parser written in Ruby, using regex patterns from the Open Podcast Analytics Working Group.
Installation:
gem 'podcast_agent_parser', '~> 0.1.9'
Then, look up your user agents like so:
agent_text = "iTunes/12.9.5 (Macintosh; OS X 10.14.5) AppleWebKit/607.2.6.1.1"
agent_parser = PodcastAgentParser::Parser.new()
parsed = agent_parser.parse(agent_text)
parsed.app # iTunes
parsed.os # macOS
parsed.device # PC
parsed.bot # false
