How to Run n8n Locally: Full On-Premise Setup (Easy Guide)

Running n8n on-premise gives you complete control over your data and workflows, which is crucial for businesses in regulated industries like healthcare, finance, or legal services. It eliminates concerns about data leaving your network and allows for custom security configurations.

On-premise installations also avoid potential cloud service outages and can be optimized for your specific hardware. Many organizations find they can achieve better performance for certain workflows by running them locally rather than sending data to the cloud and back.

• Data sovereignty: Keep sensitive information within your infrastructure
• Custom security: Implement your organization's specific security policies
• Performance: Reduce latency for internal system integrations

For basic n8n installations, you'll need at least 2 CPU cores, 4GB RAM, and 10GB of storage. These specifications can handle light development and testing workloads with a few simple workflows.

For production environments handling multiple workflows, we recommend 4+ CPU cores, 8GB RAM, and SSD storage. The exact requirements depend on your workflow complexity and execution frequency. Memory is particularly important as each workflow execution maintains its own state.

• Development: 2 cores, 4GB RAM, 10GB storage
• Production: 4+ cores, 8GB+ RAM, SSD recommended
• Enterprise: Scale horizontally with multiple workers

Yes, you can easily export your workflows from the cloud version and import them into your on-premise installation. The export includes all your node configurations, connections between nodes, and workflow settings.

The process maintains all your node configurations, credentials (though you'll need to re-enter sensitive ones), and workflow history. We recommend testing migrated workflows thoroughly as some cloud-specific integrations may need adjustment when moving to an on-premise environment.

• Export/import: Full workflow portability between cloud and local
• Credentials: Sensitive data needs re-entry for security
• Testing: Verify all integrations work in the new environment

Key security measures include setting up proper firewall rules to limit access, implementing HTTPS with valid certificates to encrypt traffic, and using strong authentication methods to control who can access the workflow editor.

Regularly updating n8n to the latest version is critical as the project releases security patches. For enterprise deployments, consider integrating with your existing identity provider (like Active Directory) for centralized access control and implementing IP whitelisting for administrative access.

• Network: Firewall rules, VPN access, IP restrictions
• Application: HTTPS, authentication, regular updates
• Monitoring: Log review, intrusion detection

Docker provides containerized isolation, making it easier to manage dependencies and updates, while direct installation gives you more control over the environment. With Docker, all dependencies are bundled together in the container, eliminating conflicts with other software on your system.

Docker is generally recommended for most users as it simplifies deployment and maintenance. Direct installation might be preferred when you need to deeply customize the runtime environment or integrate with specific system services that require direct access to the host machine.

• Docker: Isolated, easy updates, portable
• Direct: More control, deeper system integration
• Choose: Docker for simplicity, direct for customization

For Docker installations, updates typically involve pulling the new container image and restarting your n8n container. This process takes just minutes and maintains all your workflows and settings since they're stored separately in volumes.

For direct installations, you'll update via npm using npm update -g n8n. Always back up your workflows and database before updating. Consider testing major updates in a staging environment first to identify any potential compatibility issues with your existing workflows.

• Docker: Pull new image and restart container
• Direct: Run npm update command
• Always: Backup first, test when possible

Absolutely. n8n supports horizontal scaling through its queue mode, allowing you to distribute workflow execution across multiple workers. This lets you handle increased workload by adding more worker servers rather than upgrading a single large server.

For high-availability setups, you can run multiple n8n web instances behind a load balancer with a shared database. The platform has been successfully deployed in enterprises handling thousands of workflow executions per day by properly architecting the scaling approach.

• Queue mode: Distribute execution across workers
• HA: Multiple web instances with load balancing
• Enterprise: Proven at scale with proper architecture
