As the title of this question already reveals: What is the difference between the @Online and @WWW literature type in BibLaTeX?

    Documentation clearly says that www is "An alias for @online, provided for jurabib compatibility."

According to the biblatex documentation on page 13, §2.1.2 Type Aliases,

[@www is] An alias for @online, provided for jurabib compatibility.

In Appendix A you'll find a definition that for @www amounts to

    \step[typesource=www, typetarget=online]

This means that Biber converts all @www references to references of type @online. This happens even before biblatex gets to see these references. So as far as biblatex is concerned, there is no type @www, there is only @online.

    I totally imagine biblatex standing there, in its own world, its own reality, its own filter bubble going: "there is no type @www, there is only @online". How sad for biblatex to not know the whole scope of the truth!

    @thymaro But maybe it is better that way. biblatex does not need to know about the differences between @www and @online (what differences, anyway?) and can happily work on more important matters, blissfully unaware of the fact that the BibTeX world is fragmented and inconsistent at times.
