I need a free (no credit card) hosting for a NodeJS server. I've tried a couple like railway but the websocket are not going through.

Any suggestions would be appreciated 

It's not going to be easy to find free hosting for a server. Those cost quite a bit to upkeep.

If you really don't want to pay another service, you are going to have to host it yourself, on your own computer.

there are some other issues server dont cost that much.

I got a server from hertzner its like 4-5$ per month. 1month is probably enough, hopefully
