## What it is
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

## Facets
- artifact type: library
- maturity: abandoned
- function: parser, nlp
- domain: web-development, analytics, developer-tools
- platform: cross-platform
- tags: user-agent-parsing, browserscope, multi-language, archived, regexes
