n8n is a workflow automation platform that combines a visual, node-based builder with the flexibility to add custom code. It allows users to connect applications, APIs, databases, and services into automated workflows, making it possible to move data, trigger actions, transform information, and coordinate multi-step business processes from one interface.

The platform is designed for both technical and non-technical automation work. Users can build workflows visually while developers can extend them with JavaScript, custom nodes, APIs, and self-hosted infrastructure. n8n also supports AI-oriented workflows, allowing language models and other AI components to be combined with conventional integrations and business logic.

n8n can be self-hosted for greater control over infrastructure and data, while a hosted cloud service is also available. This combination makes it useful for individual automation projects as well as production workflows where teams need more control, extensibility, and deployment options than simpler no-code automation tools provide.
