luiWhat is N8N? Complete Guide 2026
Learn everything about N8N: what it is, how it works, main features and why it is the best open-source alternative to Zapier for process automation.
If you work with technology, digital marketing or process management, you've probably heard of workflow automation. Tools like Zapier and Make (formerly Integromat) dominated this market for years, but an open-source alternative is gaining more and more space: N8N. In this comprehensive guide, we'll explore everything you need to know about this powerful tool.
What is N8N?
N8N (pronounced “n-eight-n”) is an open source workflow automation platform. Created by Jan Oberhauser in 2019, the tool allows you to connect different applications and services to automate repetitive tasks, all through an intuitive visual interface.
The name “N8N” comes from “nodemation” (a combination of “node” and “automation”), reflecting the node-based architecture that makes the tool so flexible. Each node represents an action or integration, and you connect these nodes to create complete workflows.
Unlike other automation tools, N8N can be self-hosted (self-hosted), meaning you have full control over your data and infrastructure. This feature is especially important for companies that deal with sensitive data or that need to meet compliance requirements such as LGPD.
How does N8N work?
The operation of N8N is based on three fundamental concepts:
Nodes
Nodes are the building blocks of your workflows. Each node performs a specific task, such as sending an email, querying a database, or processing data. N8N offers over 400 pre-built nodes for the most popular services on the market.
There are different types of nodes:
- Trigger Nodes: Start the workflow based on an event (e.g. new email received, webhook triggered, scheduling)
- Action Nodes: Execute an action in an external service (e.g. create a record in Google Sheets, send a message in Slack)
- Function Nodes: Allows you to write custom JavaScript or Python code to transform data
- Flow Nodes: Control the execution flow (e.g. IF/ELSE conditionals, loops, data merge)
Connections
Connections link nodes together, defining the path that data takes. A node can have multiple outputs, allowing you to create parallel or conditional flows.
Workflows
A workflow is the combination of nodes and connections that forms a complete automation. You can have simple workflows with two or three nodes, or create complex automations with dozens of steps, conditionals and error handling.
N8N Key Features
Drag-and-drop visual interface
The N8N interface is designed to be accessible to everyone. You literally drag nodes onto the canvas and connect them visually. You don't need to write code to create powerful automations, although this option is available to anyone who needs it.
400+ native integrations
N8N connects with hundreds of popular services, including:
- Communication: Telegram, Slack, Discord, Gmail, Outlook
- CRM and Sales: HubSpot, Salesforce, Pipedrive
- Productivity: Google Sheets, Notion, Airtable, Trello, Asana
- Development: GitHub, GitLab, Jira
- Marketing: Mailchimp, ActiveCampaign, Meta Ads
- Databases: PostgreSQL, MySQL, MongoDB, Redis
- AI and Machine Learning: OpenAI, Anthropic, Google AI
Custom code when necessary
Despite being low-code, N8N allows developers to add JavaScript or Python code at any point in the flow. This gives you full flexibility for complex data transformations or integrations with custom APIs.
Robust error handling
N8N offers sophisticated error handling mechanisms: automatic retry, fallback streams, error notifications, and detailed execution logs. This ensures your automations are reliable in production.
Workflow versioning
Every change to your workflows is automatically versioned. This allows you to roll back to previous versions if something goes wrong, facilitating iterative development.
Webhooks support
The N8N can receive and send webhooks, allowing integration with virtually any service that supports this technology. This makes it extremely versatile as a central automation hub.
