What is n8n?
Think of n8n as a digital assembly line for your applications. It connects your different tools and services, allowing you to build automated processes (workflows) with little to no code.
The Core Concepts
n8n is built on a few simple but powerful ideas. Understanding these building blocks is the key to unlocking its potential for automation.
Nodes
Nodes are the individual workers on your assembly line. Each node represents an app (like Gmail, Slack, or Google Sheets) or a function (like an IF condition or data merge). It performs a single, specific task, like reading data, sending a message, or making a calculation.
Connections
Connections are the conveyor belts that link your nodes together. They define the path that data takes, passing the output from one node to the input of the next. This creates a logical flow for your process, ensuring tasks happen in the right order.
Workflows
A workflow is the complete assembly line, from start to finish. It's a collection of nodes and connections that work together to perform a complex task. A workflow always starts with a trigger node, which kicks off the process automatically based on a schedule, a webhook, or another event.
Build a Simple Workflow
Let's see these concepts in action. Click on the components below to build a basic workflow that sends a Slack message whenever a new row is added to a Google Sheet.

2. Choose an Action
Key Differentiators
While other automation tools exist, n8n offers a unique combination of features that make it particularly powerful for certain users and scenarios.
🏠 Self-Hosting & Data Privacy
You can run n8n on your own servers. This gives you complete control over your data, which is crucial for sensitive information and compliance with regulations like GDPR. It also means you aren't limited by another company's platform constraints.
🤸♂️ Unmatched Flexibility
n8n's node-based system allows for incredibly complex logic, including branching paths, merging data from multiple sources, and looping. For developers, you can even write custom JavaScript directly within a node to handle unique edge cases.
🤝 Fair-Code & Community
n8n is source-available under a "fair-code" license. This means you can see the code and contribute, fostering a strong community. While there are commercial restrictions, it offers much of the transparency and collaborative spirit of open-source.
Popular Use Cases
n8n is used to automate a vast range of tasks across different business functions. Explore some of the most common categories by clicking on the chart bars below.

What is n8n?
Think of n8n as a Digital Assembly Line for your apps and data. It connects all your tools to automate complex processes with visual workflows.
The 3 Core Building Blocks
Nodes
These are the individual workers. Each node is an app (like Slack or a database) or a function (like an IF statement) that performs one specific task.
Connections
These are the conveyor belts. They pass data from one node to the next, defining the order and flow of your automation from start to finish.
Workflows
This is the entire assembly line. A workflow is the complete chain of nodes and connections that accomplishes your automated task.
How a Workflow Operates
1. Trigger
A workflow starts automatically based on an event, like a new web form submission, a schedule, or a new email.
2. Actions
The data flows through a series of nodes that perform actions: formatting data, sending messages, updating databases, etc.
3. Output
The workflow completes its task, resulting in a final output, such as a report being generated or a user being added to a CRM.
Why Choose n8n? The Power Trio
🏠 Self-Hosting & Data Control
Run n8n on your own servers for complete control over your data. Perfect for sensitive information and ensuring privacy compliance.
🤸♂️ Unmatched Flexibility
Create complex workflows with multiple branches, data merging, and even custom JavaScript code for any scenario you can imagine.
🤝 Fair-Code & Community
Benefit from a source-available model that fosters community collaboration and transparency, similar to open-source.

Explore Common Use Cases
The power of n8n is best understood through real-world examples. From developer operations to marketing automation, it can connect almost any service. Use the filters below to explore workflows tailored to different business functions.
GitHub Issue from Support Ticket
When a new ticket is created in Zendesk with a "bug" tag, automatically create a corresponding issue in a specific GitHub repository.
Sync Leads to CRM
When a user submits a form on your website (via webhook), enrich the contact data with Clearbit and add it as a new lead in Salesforce.
Automated Proposal Generation
When a deal in HubSpot reaches the "Proposal" stage, automatically generate a personalized PDF using data from the deal and send it via Gmail.
Server Status Alerts
Every 5 minutes, ping a list of production servers. If a server is unresponsive, send a high-priority alert to a specific Slack channel.
Social Media Post Scheduling
Read new blog post titles and links from an RSS feed, generate a short summary with AI, and schedule posts across Twitter and LinkedIn.
New Customer Onboarding
When a customer makes a purchase in Stripe, create a user account, add them to a welcome email sequence in Mailchimp, and send a welcome DM in Discord.
Financial Workflow

Workflow Purpose
The goal of this workflow is to automate the analysis of publicly available competitor financial reports. Instead of a financial analyst manually downloading, reading, and summarizing each report, this system automatically processes new documents and generates a concise, AI-powered summary. This frees up the analyst's time for deeper strategic work and provides the team with timely, actionable insights.
