There are plugins and addons for now I didn’t felt limited when i ran a speech to text engine in game mode to chat more easily in games.

It heavily depend on you internet provider too. In France if you use orange you will have many trouble self hosting, they split IP to multiple users, and your livebox disconnect your IP and port range you were on change. For some time I have to pay for a tiny vps to manage orange port redirections. And emails need some specific DNS configuration which they never did for me. My actual provider is great for self hosting, I sent them an email and the created all the required DNS entry to make hosting email possible.
