Definition
n8n (pronounced "n-eight-n") is an open-source workflow automation platform that allows users to connect different applications, services, and APIs to automate business processes. It provides a visual, node-based interface where users build workflows by connecting blocks that represent different actions, triggers, and logic steps.
What distinguishes n8n from other automation platforms is its open-source nature and self-hosting capability. While platforms like Zapier and Make.com are fully cloud-based SaaS products, n8n can be installed on your own server, giving you complete control over your data and workflows. It also offers a cloud-hosted option for those who prefer a managed service.
n8n supports over 350 integrations out of the box, including popular business tools like Slack, Google Sheets, HubSpot, Salesforce, Twilio, Gmail, Airtable, and many more. For services without a pre-built integration, n8n provides HTTP request nodes that can connect to any API, along with custom function nodes that allow JavaScript code execution for complex logic.
The platform is particularly powerful for AI automation workflows. Users can build workflows that trigger AI phone calls based on CRM events, process incoming messages through language models, route leads based on AI analysis, and orchestrate complex multi-step processes that combine AI capabilities with business tool actions.
n8n's pricing model is attractive for businesses that run high volumes of automations. Unlike per-task pricing models that scale linearly with usage, n8n's self-hosted version has no per-execution fees. The cloud version offers generous execution limits at competitive prices.
Why It Matters for Business
n8n is the backbone of many AI automation setups. It serves as the orchestration layer that connects AI tools (like voice agents and chatbots) with business systems (like CRMs and calendars). For businesses that want maximum flexibility and control over their automation, n8n provides the power of custom development with the accessibility of a visual builder. It is especially popular among agencies and automation consultants who build solutions for multiple clients.
Real-World Example
A marketing agency uses n8n to power their client automations. One workflow monitors a client's Facebook Lead Ads, immediately triggers an AI voice call to new leads, logs the call results in GoHighLevel CRM, sends the lead a text message with a booking link, and notifies the client's sales team on Slack. The entire workflow was built visually in n8n without writing a single line of code, and it processes hundreds of leads per month reliably.
