This is a java library that tries to parse and analyze the useragent string and extract as many relevant attributes as possible.
The full documentation can be found here https://yauaa.basjes.nl
A bit more background about this useragent parser can be found in this blog which I wrote about it: https://techlab.bol.com/making-sense-user-agent-string/
As an example the useragent of my phone:
Mozilla/5.0 (Linux; Android 7.0; Nexus 6 Build/NBD90Z) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.124 Mobile Safari/537.36
is converted into this set of fields:
|Device Name||Google Nexus 6|
|Operating System Class||Mobile|
|Operating System Name||Android|
|Operating System Version||7.0|
|Operating System Name Version||Android 7.0|
|Operating System Version Build||NBD90Z|
|Layout Engine Class||Browser|
|Layout Engine Name||Blink|
|Layout Engine Version||53.0|
|Layout Engine Version Major||53|
|Layout Engine Name Version||Blink 53.0|
|Layout Engine Name Version Major||Blink 53|
|Agent Version Major||53|
|Agent Name Version||Chrome 53.0.2785.124|
|Agent Name Version Major||Chrome 53|
You can try it online with your own browser here: https://try.yauaa.basjes.nl/.
If you really like this then run it on your local systems. It's much faster that way. A ready to run docker image that can be used in both local mode and also in Kubernetes: (more info).
With docker installed do
docker pull nielsbasjes/yauaa docker run -p8080:8080 nielsbasjes/yauaa
and then open
Stefano Balzarotti is putting a lot of effort into porting Yauaa to run in .NET standard.
