I'm running n8n now, and used Node-RED several years ago.
I'm ultimately coming to the conclusion that I prefer Node-RED. They're pretty similar in capability, at least for my purposes, and the modern UX of n8n doesn't make up for its weird license, in-app upsells (e.g. "this feature is only available on the Enterprise plan"), and increasingly AI-centric functionality.
