What are the commercial use restrictions for self-hosting n8n under its license?

The key issue relates to what counts as “internal business use” versus providing n8n as part of a commercial service to external clients.

• Self hosting for internal purposes:
  You are allowed to self-host n8n for your internal business operations (for example, automating workflows within your company) even if your organization is commercial. This use falls under the Sustainable Use License.

• Self hosting as a core component of a web app/service/SaaS for clients:
  If your product or service derives its value primarily from n8n (for example, offering n8n-powered workflow automation to your external clients or white-labeling n8n), this amounts to a type of commercial use that is not permitted under the standard Sustainable Use License.

• Embed usage:
  However, n8n does offer an Embed option. With an embed license/key, you can integrate (or white label) n8n into your product for clients. This commercial use is allowed as long as you obtain the proper Embed license.

In summary, while internal business use of self-hosted n8n is permitted under the Sustainable Use License, using it to drive a commercial product or service for your clients requires an Embed license.
