n8n

n8n is an open-source workflow automation platform that connects apps, APIs, and AI models to build powerful automated workflows.

Definition

n8n (pronounced "nodemation") is an open-source, fair-code licensed workflow automation platform that enables users to connect applications, APIs, and AI models through a visual node-based interface. Founded in 2019 by Jan Oberhauser, n8n has become one of the most popular automation tools among developers and technical users who need flexibility beyond what closed-source platforms like Zapier offer.

n8n provides over 400 native integrations, supports custom code execution in JavaScript and Python, and offers both a free self-hosted community edition and managed cloud plans. Its ability to integrate directly with large language models makes it a leading platform for building AI-powered automation workflows.

How It Works

In n8n, automations are built as workflows composed of individual nodes. Each node performs a specific function — triggering the workflow, processing data, calling an API, running code, or performing an action in a connected application. Nodes are connected visually by dragging lines between them, creating a clear flow of data from trigger to output.

Workflows can be triggered by webhooks, schedules (cron), external events, or manual execution. Data passes between nodes as JSON objects, which can be transformed, filtered, merged, and routed using built-in nodes. For AI use cases, n8n provides dedicated nodes for OpenAI, Anthropic, and other LLM providers, as well as vector store integrations for retrieval-augmented generation.

n8n can be self-hosted on any server using Docker, making it ideal for users who need full control over their data and infrastructure. The cloud version eliminates server management while providing the same feature set.
