Thankyou for the reminder, long term Node-RED user here, I recently looked again at n8n and wondered why I never took it to far, this is the reason. When you see a git icon and repo it's easy missed.
The license looks quite permissive though as long as you're not using n8n as the platform for your business. According to the license, if you just wrap/productize the flows you create and users don't bring their own n8n credentials or API keys, then you're good. It seems like there's a ton you can build off of it and still stay within the parameters of the license.
Yup. Always makes sense to read the actual license too. I did that today and learned n8n changed their license in 2022. So you could look at the licenses before 2022 as well.
