We have been working hard since October to have functional and secure SaaS https://www.rodened.com service where other makers can set up their own Node-RED server prebuilt with GitHub OAuth login and Git versioning.
I built it by wiring together Google Cloud Platform, GitHub, Partial.ly, Stripe, Netlify, StackBit, and of course Node-RED.
My brother is building all kinds of workflows in Node-RED such as chatbots with ML/AI enhanced dialogue.
The next step will be to build a React dashboard app where our users can select memory, CPU, etc. Right now we have a GCP backend that receives webhooks from Partial.ly and then run an IC pipeline to build up the server container for each subscriber.
