Yauaa: Yet Another UserAgent Analyzer
This is a java library that tries to parse and analyze the useragent string and extract as many relevant attributes as possible.
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/
The full documentation can be found here https://yauaa.basjes.nl
Example output
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:

NOTES
- This runs under a "Free quota" on Google AppEngine. If this quota is exceeded then it will simply become unavailable for that day.
- After a while of inactivity the instance is terminated so the first page may take 15-30 seconds to load.
- If you really like this then run it on your local systems. It's much faster that way.
