What is ua-parser?

ua-parser is an open-source and community-driven, regexp-based user-agent parser. It has been ported to many different programming languages all of which share the same parser.

Structure

ua-parser now has its own GitHub org which contains:

• uap-core: This is the core parser shared by all language ports. Also contains the test suite.
• uap-ref-impl: A reference implementation written for node.js.
• ua-parser.github.io: The repository for this website. It also doubles as the home of this project where all meta issues are filed.

A number of language ports are also hosted within this org, including ports written in:

• C++
• C#
• D
• Go
• Haskell
• Java
• Perl
• PHP
• Pig
• Python
• R
• Ruby

FAQ

A user agent string isn't parsed properly, what do I do?

Try parsing it here. This should run the latest parser. If that doesn't work, you found a bug (or a new browser). File an issue!
