You mean like Google Hangouts used to be, before they butchered it? I'm still mad about that - it actually was the reason I bought my first iPhone. I no longer have a messaging system that does everything on Android, so I switched ecosystems for iMessage.

Or how Google talk was before hangouts. With talk, at least, you could use any XMPP client, and the web ui was wonderful for the time.
