Does anyone here have any recommendations for free or at least very cheap Rails hosting for a toy app just for learning purposes? I’m looking for a PaaS offering since I don’t have the time to secure and manage a VPS.
You'll still be spinning up a VPS, but at least set up and management is done via a very heroku-like interface from your local machine. Just get any VPS that will be accessible via SSH, and `kamal setup` can handle the rest. [1]
The one annoying part right now, is it relies on a docker registry you have to provide. I think they're working on removing that requirement, but you can use the free github container registry until then. It's just for rollbacks AFAIK.
Should also point out the recently released Rails 8, has as key features focussed on making rails much easier to deploy to anywhere that supports Docker.
