There is always free oracle cloud if you know how to setup linux web server. oracle.com/au/cloud/free/ You get two free servers with 1 cpu and I think 1 GB ram. For domains there is freenom.com (Works only on Google Chrome, I don't know why) I have oracle free tier for more than two years and It's ok, but I would sugest to always have a backup. It is ok solution for testing purposes but I would not suggest it for production.
