n8n

What is n8n?

n8n is a powerful workflow automation platform that enables users to connect applications, automate processes, and build complex integrations without extensive coding. Pronounced “n-eight-n” or “nodemation,” this open-source tool provides a visual workflow builder where users drag, drop, and connect nodes representing different services and actions. The platform bridges the gap between enterprise automation tools and accessible no-code solutions, offering both visual simplicity and technical depth.

What distinguishes n8n from competitors like Zapier or Make is its self-hosting capability and source-available license. Organizations can deploy n8n on their own infrastructure, maintaining complete control over data and workflows. This approach addresses security and compliance requirements that prevent many enterprises from using cloud-only automation services. The platform processes sensitive data locally rather than routing it through third-party servers.

n8n supports over 400 integrations covering popular services from Slack and Google Workspace to Salesforce and custom APIs. The visual workflow editor makes automation accessible to non-developers while the ability to write custom JavaScript code within workflows satisfies technical users who need flexibility. Whether automating simple notifications or building complex data pipelines, n8n provides the tools to create reliable, maintainable automation workflows.

Key Features

• Visual Workflow Builder: Intuitive drag-and-drop interface for creating automation workflows. Connect nodes representing triggers, actions, and transformations without writing code.
• 400+ Integrations: Pre-built connectors for popular services including Google Workspace, Microsoft 365, Slack, Salesforce, HubSpot, databases, and many more.
• Self-Hosting Option: Deploy on your own servers or cloud infrastructure. Maintain complete control over data, ensuring compliance with privacy regulations and security requirements.
• Code When Needed: Write custom JavaScript or Python code within workflows for complex transformations, custom logic, or integrations with APIs lacking native connectors.
• Error Handling: Built-in error handling with retry logic, fallback paths, and error notifications. Workflows continue running or fail gracefully based on configuration.
• Webhook Support: Create webhook endpoints to trigger workflows from external systems. Accept incoming data and process it through automation pipelines.
• Scheduling: Schedule workflows to run at specific times or intervals. Cron expressions support complex scheduling requirements.
• Version Control: Track workflow changes with built-in versioning. Roll back to previous versions and review modification history.
• Credential Management: Secure credential storage for service authentication. Share credentials across workflows without exposing sensitive values.
• Community Nodes: Extend functionality with community-contributed nodes. Create and share custom integrations through the n8n community.

Frequently Asked Questions

Is n8n really free?

Self-hosted n8n is free for unlimited workflows and executions under the Sustainable Use License. The cloud version offers a free tier with limited executions. Paid plans add features like more executions, team collaboration, SSO, and priority support. The self-hosted free option is genuinely useful for production workloads, making n8n accessible to organizations of any size.

How does n8n compare to Zapier?

Zapier offers more integrations (5000+ vs 400+) and a simpler interface suited for non-technical users. n8n provides self-hosting, custom code capabilities, and more complex workflow logic. Zapier charges per task/operation while n8n self-hosted is unlimited. Choose Zapier for simplicity and maximum integrations; choose n8n for control, flexibility, and cost management at scale.

Can n8n handle high-volume automation?

Yes, with proper infrastructure. n8n supports horizontal scaling, queue-based execution, and database backends designed for high throughput. Production deployments handle millions of executions. Performance depends on server resources, workflow complexity, and external service rate limits. The execution engine is optimized for efficiency, and webhook response times are typically measured in milliseconds.

Is my data secure with n8n?

Self-hosted n8n keeps all data on your infrastructure—nothing leaves your servers unless workflows explicitly send data externally. Credentials are encrypted at rest using your encryption key. n8n Cloud processes data through n8n’s infrastructure with SOC 2 compliance. For maximum security, self-host in your own environment with appropriate network security measures.

How do I get help with n8n?

n8n provides multiple support channels: comprehensive documentation, active community forum, Discord server for real-time help, and GitHub for bug reports and feature requests. Paid plans include priority support. The community is particularly active, with many experienced users helping newcomers. The documentation covers common use cases with workflow examples.

Final Verdict

n8n occupies a unique position in the workflow automation landscape, offering enterprise-capable features with self-hosting flexibility that cloud-only competitors cannot match. For organizations where data sovereignty, security compliance, or cost predictability matter, n8n provides genuine differentiation. The platform proves that powerful automation doesn’t require surrendering control over your data.

The visual workflow builder makes automation accessible without sacrificing depth. Non-developers can create functional workflows quickly, while technical users appreciate the ability to inject custom code for complex transformations. This dual nature makes n8n suitable for diverse teams with varying technical backgrounds.

Self-hosting does require infrastructure management skills, and organizations should honestly assess their operational capabilities before committing. For those willing to manage their own deployment—or willing to use n8n Cloud—the platform delivers exceptional value. The active development, growing integration catalog, and AI capabilities ensure n8n remains relevant as automation needs evolve. For teams seeking powerful, flexible automation with deployment freedom, n8n stands as the leading open-source option.
