I have started to learn n8n. It looks amazing! I'm in the very first stages though, having created my first workflow. I am doing a self hosted community edition, running on hetzner web hosting. Total cost is like $7 per month for unlimited number of executions. It took me a while to set up because I ran into all sorts of issues. But you can install it on your home computer very easily. I put it on a host so it is guaranteed to run executions 24/7, regardless of the status of my home computer.
