I got response from support.
I applied to free tier at https://www.heroku.com/open-source-credit-program

[romani]

I we be not accepted we can try https://railway.app/ , it has some free basic credit for each month that will be enough for our application, that has almost no traffic.

[romani]

we are approved for Free plan on Heroku, I will do deploy as credits are applied to plan.
