I haven't used Heroku's free product plan myself, but I personally use Fly for my personal blog and website and thoroughly enjoy its pain free deployment process. They also have built in secrets management which I was happy to see. There is GitHub Actions for automating things too.
They supposedly also decrease latency for your application if you migrate your Heroku app there (again, I haven't used this myself so YMMV): https://fly.io/launch/heroku
You do need to enter credit card information as mentioned in this thread.
