n8n

n8n is an open source automation platform that lets you build complex workflows through a visual interface, while still allowing full custom code at any step. It can be installed on a private server or used as a managed cloud version.

It’s built mainly for development teams, IT departments, and organizations with strict security and privacy requirements that prefer to keep their data on their own infrastructure rather than with an outside provider. It also suits tech companies that want to build complex automations at a relatively low cost over the long term.

Key capabilities include hundreds of ready made connections to apps and services, the ability to integrate AI models and build internal AI agents, and complete flexibility to write custom logic through code snippets. The platform also supports full self hosting, giving you complete control over costs and data security.

In support and automation workflows, n8n usually serves as the infrastructure layer connecting the support system, the internal database, and AI tools, making it possible to build custom processes that have no ready made equivalent in more closed tools. It’s usually chosen when an organization has the in house technical capability to maintain the system.
