I know a lot of people dismiss this thing as only being useful for RaspberryPi IOT automation, but I've been using this for a year or two now on my own personal server and I'm surprised how flexible and performant it is.

It's more than just a prototyping tool, and it has a lot of integrations designed by the community. For instance, within a couple weeks of ChatGPT being announced, there were already flows created to automate integration. https://flows.nodered.org/

I've been thinking about introducing this tool to my work as a replacement for some of the older and less-used APIs we maintain. Have you had any experience with Node-Red? Would you like to check it out? I can help you set it up if you want too, it's fun learning about this tool and what's possible with it.
