Hey, thanks for the interest! It's really cool to hear when people are interested.
I'm just finishing up one of the last features that I think is necessary for a public release - connecting to multiple Factorio servers. If all goes well I'll publish it on GitHub.
I've worked on the setup so if you have a Factorio server all you need to do is install the mod, ask for an API key, and set up a way of forwarding the logs. If you want to host the backend Kafkatorio infra, then you can do so with a Docker Compose file.
Watch this space!
