I agree with you. It seems like the self-hosting community is getting a decent bit of attention right now, and the ability to deploy browser-based applications is the way to go for many FOSS projects.

I think NextCloud [0] has a few apps that do G Suite-type stuff, but I don't have experience using them. Etherpad [1] also seems really good, I've used it in a few Zoom calls and the experience was smooth. Personally, I'm looking for a Google Photos alternative that's stable enough for my parents to use.
