n8n

n8n uses workflows to connect a set of independent operations into repeatable processes. The process starts with a trigger—such as a scheduled task, an application event, or a form submission—and then proceeds through nodes that read data, transform fields, evaluate conditions, and invoke external services. The visual canvas simultaneously illustrates the processing steps and branching relationships, making it ideal for chaining together information that would otherwise have to be manually transferred across multiple applications.

It combines traditional rule-based automation with AI nodes in the same workflow. You can prepare data before invoking the model, validate the structure after generating results, and then route tasks based on conditions or add human confirmation. Execution logs let you review past runs and troubleshoot failed steps; the official website also offers capabilities to re-run from failed nodes and access version history. Actual permissions depend on the version and plan you’re using.

The usage options are n8n Cloud and self-hosted. The hosted version has its runtime environment maintained by n8n, while self-hosting requires you to manage servers, databases, updates, and operational security yourself. According to the official documentation, without a license key, self-hosting uses the Community edition; the extended capabilities of the Business and Enterprise editions require corresponding licenses. Self-hosting should not be interpreted as providing all enterprise features for free.

It’s suitable to start with a well-defined workflow, such as periodically fetching information and saving reports, synchronizing form data to a business system, or integrating data organization with manual approval processes. After the workflow is connected to a live account, be sure to verify credential permissions, failure branches, and retry behaviors, to avoid treating a single test run as a guarantee of long-term stable operation.

Technical teams, operations personnel, and automation developers who need to connect multiple business systems.

The above figures represent the average monthly price for the annual plan, quoted in euros. Hosting pricing is based on the number of workflow executions per month; for details on the differences between the self-hosted Community edition and the paid extensions, please refer to the official deployment documentation.
