A multi-language port of Browserscope's user agent string parser that extracts browser, device, and OS information from user agent strings. The project has been split into separate repositories under the ua-parser organization, with this original repo now serving as a pointer.

Use cases

  • parse user agent strings to detect browser and OS
  • identify devices from http user-agent headers
  • analytics on which browsers visit my site
  • multi-language user agent parser library
  • extract browser version from user agent

When to choose

  • you need user agent parsing in one of the many supported languages
  • you want a shared regex database across language implementations

When to avoid

  • starting a new project - use the split ua-parser/uap-core and language-specific repos instead
  • you need actively maintained user agent parsing with up-to-date regexes
