JarCastingYauaa: 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.
The full documentation can be found here https://yauaa.basjes.nl
HIGH Profile release notes:
Version 5.18
- Correctly classify the elements in the Google Chrome (and Chromium based MS Edge) User-Agent string that are incorrect when the "Freeze User-Agent request header" flag is enabled.
- New UDF for Elastic Search. I have done limited (local single node) testing. Please report anything you find so I can fix it.
Blog post
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/

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. 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/yauaaand then open
http://localhost:8080/

Stefano Balzarotti is putting a lot of effort into porting Yauaa to run in .NET standard.
You can track his efforts here on Github: Yauaa .NET standard and download his releases via Nuget.
