Open-source workflow automation platform with 500+ integrations, visual builder, and native AI agent support for human-supervised AI workflows.
Connect your apps and automate workflows with a visual builder â like Zapier but self-hostable and more powerful for AI workflows.
n8n is a workflow automation platform that has become one of the most popular tools for building AI-powered automations thanks to its extensive integration library, self-hosting capability, and increasingly sophisticated AI features. While not AI-native like LangChain or Flowise, n8n's approach of treating AI operations as nodes within a broader automation framework makes it uniquely powerful for workflows that combine LLM capabilities with real-world actions.
n8n provides 400+ integrations (nodes) covering CRM, email, databases, project management, communication, cloud services, and more. The AI-specific nodes include LLM calls (OpenAI, Anthropic, Google, Ollama), vector store operations, document processing, embedding generation, and agent patterns. The key advantage is that AI operations exist alongside all other integration nodes â your workflow can query an LLM, process the response, update a CRM record, send an email, and trigger a webhook, all in one flow.
The platform's AI agent node is surprisingly capable. It supports ReAct-style agents with configurable tools, memory (window buffer, PostgreSQL-backed), and multiple LLM providers. The agent can use n8n's entire integration library as tools â meaning an AI agent can search Slack, create Jira tickets, query databases, and send emails through the same interface used for non-AI automation.
n8n supports code nodes (JavaScript and Python) for custom logic, webhook triggers for event-driven workflows, cron scheduling for periodic execution, and error handling with retry logic. Workflows can be triggered by schedules, webhooks, manual execution, or other workflows.
The platform is source-available (fair-code license) and can be self-hosted via Docker or npm. n8n Cloud offers managed hosting with team features.
Honest assessment: n8n is the best choice for AI automations that need to interact with many external services. If your workflow is 'when X happens, use AI to analyze it, then do Y and Z in other tools,' n8n is ideal. It's not the right tool for pure LLM application development (use LangChain or a visual AI builder) or complex multi-agent systems (use CrewAI or LangGraph). n8n's sweet spot is practical business automation enhanced with AI capabilities.
