Buyer's guide
How to choose a user-agent parser
When picking a user-agent parser, decide whether bot identification matters for your workflow. If you need to filter Googlebot or other crawlers from your traffic data, choose a tool that explicitly lists bot detection. If you only need to decompose the string into browser, OS, and device components, a simpler parser without bot flags will suffice.
