n8n is a low-code, event-triggered workflow automation tool built with Node.js that enables users to orchestrate logic, connect services, and scale pipelines with minimal boilerplate. It offers a visual interface where users can connect nodes - each representing a step in a process - to create workflows that respond to events, run on schedules, or execute on demand. n8n is open-source and fully self-hostable, giving teams full control over data, system behavior, and deployment, with features such as hundreds of integrations, strong community support, and the ability to extend the platform however needed. The tool supports both real-time triggers and scheduled tasks, making it adaptable to nearly any automation use case. n8n's open-source model has fostered a vibrant community, where users can access public workflows, contribute new nodes, bug fixes, and guides, or get help building custom integrations. With its visual interface, LLM readiness, and strong API support, n8n stands out as a developer-first, open-source automation platform that scales from side projects to mission-critical workflows.
