Thanks for that. I understand that what you are describing is separate to what you need to pay for Dash if you want to deploy it on Heroku?
I find the following 2 points confusing: 1) The Dash pricing website https://plotly.com/dash/ says public publishing is not available for opensource. 2) Deploy Dash app interprise for free.
So will publishing an opensource app at Heroku be possible and entirely free or do I need to pay for a non-opensource Dash pricing plan and then publish for free on Heroku? I’d very much appreciate clarifying this.
