Running Node.js in Google Cloud Shell – Is it Free?

I'm very new to all of this, so please tell me anything I'm doing wrong!

I wrote a little bot for Discord using Node.js.

I also signed up for the free trial of Google Cloud Platform wth $300 of credit and all that. After creating a project, I started the cloud shell and ran my Node.js Discord bot using:

node my_app_here.js

The cloud shell is running and the bot is working correctly. Will the cloud shell run indefinitely and keep my bot running? It seems hard to believe that Google would host my bot for free. I have billing disabled on the project, but I'm afraid of getting hit with a huge bill.

Thanks for any help or recommendations!
