      For doing proper analytics on website visitors I want to pick the User-Agent string apart and report the correct name of the used Browser and it's version. I have written some software to do that which is used by many people: Yauaa

      For many browsers (Chromium, Chrome, Edge, Firefox and others ) I have been able to find a good specification of the patterns to look for and what they mean.

      For Opera I have not been able to find such a specification and I had to resort to installing all Opera variants on the devices I have (and ask friends to do so also) and do reverse engineering based on that data.

      I would like to have documentation for all Opera variants (Desktop, Mini, Mobile, GX, ...) the User-Agent formats and some examples (similar to what I see for Firefox).

      I need clear specs for tags like Opera, OPR/, OPiOS/, OPRGX/, ... and strange things (that I think is the case) when OPR/ is on Android in a webview that it really Opera Mini.

      I would also like to have at least a single real example for each browser on each platform (Windows, MacOS, Linux, Android Phone, Android Tablet, iPhone, iPad) the User-Agent and the UA-ClientHints that are used.
