Self-hosted Community runs indefinitely without a paid license key. Registered Community also remains free. Business/Enterprise features and n8n Cloud are paid; your server, third-party services and model APIs can add costs. Its source-available license is not a general permission to sell a competing service.
Connect applications and build visual workflows, with code available for custom steps. A self-hosting option is recorded for this project. Review the official deployment instructions and maintenance requirements before running it yourself.
