Hello everyone! Does anyone use the prefect on heroku?

Hi @Gabriel Santos - I can't say I've used prefect on Heroku personally but I've used both in the past. Did you have a specific question?

I am new a both tools, and want to test prefect on heroku, do you now how to configure procfile and configure database conn to heroku postgres?

Unfortunately that's not something I'll be able to help with - those will be pretty specific to Heroku. If you're in the testing phase I'd recommend deploying Prefect Server locally or on a single cloud container of your choice
