If you have a useragent, and you don't know which OS, Platform etc it is, you can take a look here:

?https://www.browscap.org/ua-lookup

Example i use the google bot useragent:

Code:
Mozilla/5.0 (X11; CrOS x86_64 13729.72.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.116 Safari/537.36

Paste the useragent in the "User Agent:" input field and click "Look up »".

This is a great website for developer as well as for normal spammers to identify where the user agent comes from.

Why for developer?

Because you can block those User-Agents by regex:
Code:
/^mozilla\/5\.0 \(.*cros x86_64.*\) applewebkit.* \(.*khtml.*like.*gecko.*\) chrome\/89\.0.*safari\/.*$/

Why for users?

Because you know the platform, what your victim is using.

Code:
browser_maker   Google Inc

And yes and actually don't know if it's very good to block those chrome OS useragent's but they are related to google and google safebrowsing fuck up your scampage immediately.
