Affordable Server Recommendation for Node.js

[Hashigato]

Hello, I have a free server from render.com with 512 MB RAM and 0.1 CPU. I need to move to a new server as I have built the site with node.js. If there is a 1-month trial membership available, it would be great on the site you recommend. Otherwise, I can spend a maximum of $5, etc. What I really want is for the site to be able to handle around 10 people entering at the same time without struggling, and to do this at the lowest budget possible. How can I achieve this?
