n8n

n8n is an open-source workflow automation tool that has expanded heavily into AI agent orchestration, letting teams build automations that combine traditional app integrations with LLM reasoning steps.

## Core Capabilities

**Visual Workflow Builder** Drag-and-drop canvas for connecting triggers, actions, and conditional logic across 400+ app integrations (Slack, Gmail, Airtable, databases, and more).

**AI Agent Nodes** Native nodes for calling LLMs (OpenAI, Anthropic, and others), running RAG pipelines over vector stores, and building autonomous agents that can call other workflow nodes as "tools."

**Self-Hostable** Can run entirely on a company's own infrastructure (Docker, npm) for teams with data-residency requirements, alongside a hosted cloud version.

**Code Nodes** Drops into JavaScript/Python for custom logic when the visual builder isn't enough, without leaving the workflow canvas.

## Positioning Competes with Zapier and Make on traditional automation, differentiated by open-source self-hosting and deeper native AI-agent building blocks.

## Pricing Free self-hosted (community edition); paid Cloud plans start around $20/month, with enterprise tiers for larger teams.
