Plugins via web-interface?

Hey everyone, longtime plex user here, and I’ve become very interested in some plugins (wont say which one, as im not sure if you’re allowed to)… but a few things about kodi have confused me and googleing has only gotten me so far. MY main question is this; Is there any way to use plugins via the webinterface? I want to just have kodi running on a remote dedicated server I own, and access it from browsers elsewhere. Is this possible? or am I thinking the “plex way”

I have gotten somewhat there. I select what I want to watch, and then I click it (Via the web interface) but it will only give me the choice to choose the source via the local client, not the remote web interface…. and Im stuck after that. Is it just impossible and I have to install the Kodi client on EVERY computer I want to use? It just seems really more of a hassle then I have time for Sad

Thanks in advanced
