tldr: it depends but probably not, but there are ways “around” it.
Disclaimer, im not a lawyer or part of the n8n team, send the n8n team an email if you aren’t sure, they are always very nice and helpful
That being said, as someone who offers n8n services I have had to figure all of this out.
You can find n8n’s license here and an explanation of it here.
You are allowed to provide consulting services like creating workflows, nodes, providing support, etc. You are NOT allowed to offer n8n as a service. To do that you would need to pay n8n an embedding license fee (which starts at $50,000/year.)
It can get a little blurry because you’re allowed to use n8n for internal business use but you can not offer it as a service to customers without the reseller license, which i strangely cant find the page while googling. With that license you prepay for a certain amount of workflow runs on a monthly basis and can charge whatever you want to host n8n for others.
You could make the argument that if you, for example, make a backend service for a client using n8n, as long as they don’t interact with n8n then that is your “internal business” and it’s allowed. That’s as grey of a situation as I can think of.
Here’s my preferred way of handling this:
I have my clients self host their own instance, if they need the self hosted advantages like custom nodes. If not, they can just pay for the cloud version. I do prefer self hosted for the extra control you have through.
They can hire me as an IT professional to host it for them and can pay me for maintenance, but it will NEVER be in my hosting accounts or in one of my servers, always in the client’s account. Hosting somewhere like linode is only $5 a month.
Then from there you can be hired to make workflows, make nodes, etc. But make sure you’re being honest about if you’re really providing a hosting service. It should be clear and you should have a clear contract with your client stating the limitations of your services related to the license of n8n.
Let me know if you have any questions. That’s kinda a lot of information from a fairly simple question
