N8N Review: The Open-Source Workflow Automation Platform Built for Technical Teams

If you're tired of paying per-task pricing for automation tools or want complete control over your workflow data, N8N offers a refreshing alternative. This open-source automation platform combines the visual simplicity of tools like Zapier with the technical flexibility developers crave, all while keeping your data under your control.

What is N8N?

N8N is an open-source, low-code workflow automation platform founded in Berlin in 2019 by Jan Oberhauser. Unlike proprietary tools like Zapier or Make.com, N8N operates on a fair-code license, meaning its source code is publicly available and can be self-hosted on your own infrastructure.

The platform enables users to build complex workflows visually through a drag-and-drop interface while offering the flexibility to write custom JavaScript or Python code when needed. With over 400+ pre-built integrations and execution-based pricing instead of per-task charges, N8N has become increasingly popular among technical teams, developers, and businesses looking for cost-effective automation solutions.

What truly sets N8N apart is its deployment flexibility. You can choose between the free self-hosted Community Edition or the managed N8N Cloud service. This means you maintain complete control over your automation infrastructure and data, a critical advantage for companies with strict security or compliance requirements.

Key Features

Visual Workflow Builder: N8N's intuitive drag-and-drop interface lets you create sophisticated automations without writing extensive code. Each workflow consists of nodes that represent different actions, triggers, or services, connected visually to show data flow. The interface is clean and developer-friendly, making complex logic easy to understand at a glance.

400+ Native Integrations: Connect popular services including OpenAI, Anthropic Claude, Google Gemini, Slack, Notion, Airtable, PostgreSQL, Shopify, Gmail, and hundreds more. Unlike some competitors that offer shallow integrations, N8N provides deep integration options with multiple triggers and actions per application, enabling detailed automation scenarios.

Custom Code Execution: When pre-built nodes aren't enough, N8N allows you to write JavaScript or Python code snippets directly within your workflows. This capability bridges the gap between no-code simplicity and developer-level customization, making it possible to handle virtually any automation requirement.

AI-Native Capabilities: N8N positions itself as a truly AI-native platform with advanced LangChain integration, offering nearly 70 nodes dedicated to AI applications. Build intelligent chatbots, conversational assistants, document summarization tools, and information extraction workflows. The OpenAI GPT integration supports GPT-3.5, GPT-4, and newer models, enabling you to leverage cutting-edge AI within your automations.

AI Agent Framework: Create intelligent agents that can receive text input, process it using AI models, retrieve relevant information from vector stores like Pinecone, and respond based on conversational history. This opens possibilities for support bots, intelligent classification systems, and context-aware automated responses.

Self-Hosting Option: Download the Community Edition from GitHub and deploy it on your own servers, giving you complete control over your data, infrastructure, and costs. This is particularly valuable for organizations with sensitive data or strict regulatory compliance requirements.

Built-in Error Handling: N8N includes automatic error retry mechanisms to ensure workflows run smoothly. When tasks fail, the system can automatically retry them based on your configuration, reducing manual intervention and increasing reliability.

Execution-Based Pricing: Unlike competitors that charge per task or step, N8N charges based on workflow executions. An execution is a single run of your entire workflow, regardless of how many steps it contains or how much data it processes. This pricing model makes N8N significantly more cost-effective for complex, multi-step automations.

How It Works

Using N8N is straightforward, whether you choose cloud or self-hosted deployment:

1. Create a Workflow: Start by adding a trigger node that initiates your automation, such as a webhook, scheduled timer, or event from an integrated app.

2. Add Action Nodes: Drag and drop nodes representing the services you want to connect. Configure each node with your credentials and specify what actions to perform, such as sending data to a spreadsheet, generating AI responses, or updating a database.

3. Connect and Configure: Link nodes together to define the data flow. Use built-in transformation tools to map fields, apply filters, or add conditional logic that determines which path your workflow takes.

4. Test and Deploy: Run test executions to verify your workflow behaves as expected. N8N provides detailed execution logs showing exactly what data passed through each node, making debugging straightforward.

5. Monitor and Scale: Once deployed, your workflows run automatically based on their triggers. The platform handles error retries and provides execution history for monitoring performance.

Pricing

N8N removed active workflow limits from all plans in 2025, meaning every tier now includes unlimited workflows, steps, and users. Here's the current pricing structure:

Community Edition (Free): Self-host N8N on your own infrastructure at no cost. Perfect for individual developers, small teams, or organizations that want complete control. You'll need to handle your own hosting, updates, and maintenance, but there are no execution limits or feature restrictions.

Starter Plan (€20/month, billed annually): The cloud-hosted entry point includes 2,500 workflow executions per month, automatic updates, and managed infrastructure. No workflow limits mean you can create as many automations as needed within your execution allowance.

Pro Plan (€50/month): Includes 10,000 executions monthly plus advanced features like environment variables for managing different deployment stages, webhook authentication for secure API connections, and priority support. This tier suits growing teams and businesses with moderate automation needs.

Business Plan: Designed for mid-sized companies requiring enterprise-grade features with self-hosted deployment flexibility. Pricing is custom based on requirements, but includes enhanced security controls, advanced workflow management, and dedicated support resources.

Enterprise Plan: Custom pricing with unlimited executions, dedicated support, service level agreements (SLAs), advanced security features, and personalized onboarding. Built for large organizations with mission-critical automation requirements.

The execution-based pricing model means that a complex workflow with 20 steps counts as one execution, while competitors would charge for 20 tasks. For businesses running sophisticated automations, this difference can result in substantial savings as you scale.

Who Should Use N8N?

Developers and Technical Teams

If you're comfortable with code and want automation tools that don't limit your possibilities, N8N is ideal. The ability to write custom JavaScript or Python, connect to any API, and self-host gives you complete flexibility that proprietary platforms can't match.

Businesses with Compliance Requirements

Organizations in healthcare, finance, or other regulated industries often cannot send sensitive data to third-party automation platforms. N8N's self-hosting option ensures your workflow data never leaves your infrastructure, satisfying even strict compliance mandates.

Cost-Conscious Companies Scaling Automation

The execution-based pricing becomes increasingly advantageous as your automation needs grow. Companies running hundreds of complex workflows will find N8N dramatically more affordable than per-task competitors like Zapier, where costs can skyrocket quickly.
