Would you believe Oracle OCI? They have an always free tier, as in you never pay. You need a valid regular credit card. At first I thought it was for a slow x86 instance, but it includes Arm hours equivalent to 4 cores, 24 GB RAM, 10TB of transfer a month, I think 200GB storage. Divide it up for an nginx reverse proxy in front of it, or HA Proxy if you are feeling ambitious.
