n8n Self-Hosted: Open-Source Workflow Automation Platform

n8n self-hosted workflow automation platform empowers technical teams to build powerful automations while maintaining complete control over their data. Unlike cloud-based alternatives like Zapier or Make, n8n self-hosted runs entirely on your infrastructure, giving you flexibility, privacy, and scalability without vendor lock-in.

What is n8n Self-Hosted?

According to the official n8n GitHub organization, n8n is a fair-code licensed workflow automation platform that combines the flexibility of code with the speed of no-code. With over 400 integrations, native AI capabilities, and a visual workflow editor, n8n self-hosted lets you build sophisticated automation while keeping all data on your servers.

The name n8n stands for "nodemation," reflecting its node-based approach to building workflows. Founded in 2019 by Jan Oberhauser, n8n has grown to become one of the top 150 projects on GitHub with over 80,000 stars and more than 100 million Docker pulls.

Key Features of n8n Self-Hosted

n8n self-hosted comes packed with features that make it a powerful automation platform:

Visual Workflow Editor: Build complex automations using an intuitive drag-and-drop interface. Connect nodes, establish conditional logic, and observe execution flow in real-time directly within the editor.

400+ Integrations: Connect with GitHub, Google Sheets, Slack, MySQL, AWS, Discord, Trello, and hundreds more services. This extensive library enables automation across cloud platforms, databases, messaging apps, and developer tools.

Native AI Capabilities: With LangChain integration, n8n self-hosted allows you to build AI-powered functionality within workflows. Create AI agents, chatbots, and intelligent automation that leverages large language models.

JavaScript Support: Insert custom JavaScript code directly into workflows using built-in Function and Function Item nodes. This empowers you to transform data and implement business logic beyond standard integrations.

Self-Hosting n8n with Docker

The recommended way to run n8n self-hosted is using Docker Compose. This provides a robust, production-ready deployment with database persistence and easy upgrades.

Quick Start with Docker:

docker run -it --rm   --name n8n   -p 5678:5678   -v ~/.n8n:/home/node/.n8n   n8nio/n8n

Production Docker Compose Setup:

version: '3'
services:
  n8n:
    image: n8nio/n8n
    ports:
      - "5678:5678"
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=your-username
      - N8N_BASIC_AUTH_PASSWORD=your-password
    volumes:
      - ~/.n8n:/home/node/.n8n

One-Command AI Installation

For users who want a complete AI automation environment, the community has created comprehensive installers. According to the n8n-install repository by kossakovsky, you can deploy 30+ AI and automation tools with a single command:

git clone https://github.com/kossakovsky/n8n-install && cd n8n-install && sudo bash ./scripts/install.sh

This setup includes n8n, Ollama for local LLMs, Flowise for AI agents, vector databases (Qdrant, Weaviate), Supabase, monitoring with Grafana and Prometheus, and automatic HTTPS with Caddy.

System Requirements

n8n self-hosted has modest resource requirements:

• CPU: 2+ cores recommended
• RAM: 2GB minimum, 4GB+ recommended
• Storage: 1GB minimum for application, more for workflow data
• Operating System: Linux, macOS, or Windows with Docker

For production deployments with queue mode and multiple workers, additional resources are recommended based on workflow volume.

Event-Driven Workflow Execution

n8n self-hosted supports multiple trigger types for event-driven automation:

• Webhooks: Trigger workflows via HTTP requests from external services
• Scheduled: Run workflows on cron schedules for recurring tasks
• Application Events: Respond to events from connected services like new emails or database changes
• Manual: Execute workflows on-demand through the UI

AI and LangChain Integration

n8n self-hosted includes native LangChain nodes for building AI-powered workflows:

• AI Agent Chat nodes for conversational interfaces
• Vector Store connections for RAG applications
• LLM nodes supporting OpenAI, Anthropic, and local models via Ollama
• Document loaders for processing PDFs, text files, and web content

The official n8n AI template gallery provides ready-to-use workflows for common AI use cases.

Security and Access Control

n8n self-hosted provides robust security features:

• Basic authentication with username and password
• HTTPS support for encrypted connections
• Webhook signing for verifying request authenticity
• Credential encryption for secure API key storage
• User management and role-based access in enterprise versions

Production Deployment Considerations

For production n8n self-hosted deployments, consider these best practices:

• Use PostgreSQL instead of SQLite for better performance and reliability
• Enable queue mode with Redis for handling high workflow volumes
• Set up proper backup procedures for workflow and credential data
• Configure monitoring and alerting for system health
• Use a reverse proxy like Nginx or Caddy for SSL termination

Why Choose n8n Self-Hosted?

n8n self-hosted offers a unique combination of power, flexibility, and control. The visual workflow editor makes it accessible to non-developers while the JavaScript support and API provide depth for technical users. With 400+ integrations and growing, it can connect virtually any service you use.

The fair-code license ensures the platform remains open and self-hostable, while the active community and commercial backing provide confidence in long-term development. For teams that need workflow automation without sacrificing data privacy, n8n self-hosted is an excellent choice.
