n8n Tutorial: Self-Hosting Open-Source Automation for Free

By Marco Gundlach Last updated on November 14, 2026

Imagine building automations without paying for a subscription every month and without having to worry about usage limits. That is exactly what n8n promises. The title of the video mentions Google Opal, but the content is entirely about n8n. This guide walks you through the platform: from the basics to the cloud version to your first own workflow.

Key Takeaways

• n8n is an open-source automation platform that you can run on your own servers for free.
• The software offers over 500 integrations and is intended equally for developers, teams, startups, and power users.
• Costs arise mainly from server operation when self-hosting, or from cloud subscriptions and the use of external services such as AI interfaces.
• The cloud version is ready to use immediately, while the self-hosting version offers full control and data sovereignty.
• For getting started, simple processes such as "form to email" are well suited, before you build complex AI agents.

Step 1: What n8n actually is

Before you get started, it's worth taking a brief look at the basic principle. n8n belongs to the family of automation tools like Zapier or Make. You connect services with each other so that tasks run automatically, for example when a form is submitted and a message appears in the chat. The decisive difference lies in the license: The software is open source and can run on your own server. This way you keep full control over your data and workflows.

Step 2: Choose the Free Edition or the Cloud

You have two ways to run it. With the free Free Edition, you download the software and install it yourself, for example with Docker. The only costs then arise for your server and possibly for the use of external interfaces. The cloud version, on the other hand, is ready to use immediately. You don't have to configure or install anything; you simply sign up, and your server is set up automatically in the background.

Pay attention to data protection with both versions. If you use the cloud in the EU, you should check the GDPR requirements carefully. An alternative is your own server in your network, which you coordinate together with your company's data protection officer.

Step 3: Explore the homepage and example workflows

On the official website, you will find lots of information about automation and AI workflows. The examples are particularly helpful. A typical scenario is the onboarding of new employees: A form triggers the process, an AI agent processes the details, and then information is distributed to various systems such as chat services or Microsoft tools. Such templates show you how complex processes are built, and you can use them as a starting point.

Step 4: Understand integrations and templates

n8n offers over 500 integrations. Compared to Zapier with over 6,000 or Make with significantly more connections, this seems like less at first. However, the speaker points out that the most important tools are included. In addition, any systems can be connected via webhooks, so you hardly run into limits.

Another advantage is the templates. Currently, almost 4,839 workflows are available, which you can filter by topics such as sales, marketing, IT, or AI. These also include examples of chatbots, Retrieval-Augmented Generation (RAG) systems, and summaries of information. Use cases such as building AI agents or security processes in IT are also covered.

Step 5: Use the documentation and community

The documentation is extensive and written in English, but it is clearly structured. There you will find instructions for installation, for example via Docker, as well as for configuration and user authentication. If you need help, a forum, a Discord server, blogs, creators, and certified partners are also available to you. A support contact is also provided. For free open-source software, this offering is remarkable.

Step 6: Compare prices and cloud plans

The pricing page distinguishes between self-hosting, cloud, and enterprise. For self-hosting, there are no license costs. In the cloud, the Starter plan starts at about 20 or 24 euros per month, depending on whether you pay annually or monthly. In the video, 2,500 workflow executions per month are mentioned, which are usually sufficient for getting started. The Pro plan costs about 60 euros and includes 10,000 executions as well as global variables, which are very useful as usage grows. Be sure to check the prices on the current website before making a decision, as they may change.

Step 7: Registration and First Login

For the cloud version, you click on "Get Started" and set a username and a password. Signing in with a Google account is not possible. After registration, a server is created in the background. You will receive a quick-start guide that takes about 15 minutes and makes the first steps easier for you.

Step 8: Getting to Know the Backend Interface

After logging in, you land in the backend. In the left menu, you will find the most important areas: Workflows, Credentials for your access data to external services, and Executions, meaning the logged runs. Via the Personal area or via projects, you organize your automations sensibly. In addition, there are Templates, Variables, as well as Settings and help resources. For beginners, the Workflows and Templates are especially relevant. The admin area only becomes interesting with paid versions and multiple users.

Step 9: Building the First Workflow with a Form, AI, and Trello

Now it gets practical. Using the plus icon, you create a new workflow. A form is supposed to send the inputs to OpenAI, have the response summarized, and then pass the result on to Trello. You start with the trigger "n8n Form Trigger". Here you define the title, description, and input fields and save the form.

In the second step, you add the OpenAI node, select a model, and store your credentials. In the prompt, you formulate the instruction, for example "Summarize the following text", and drag the output of the form into it as input.

Next comes the Trello node. You choose the action "Create a Card", store your Trello credentials, and specify the board and list. The summary is adopted as the card text. If you also want to send the result via Slack, you need a Switch node, because n8n does not create branches automatically. This point distinguishes n8n from Make, where such branches are often created automatically.

Step 10: Workflow Designer, Costs, and Best Practices

The visual workflow designer allows you to arrange building blocks via drag-and-drop. This helps with overview, especially when a process consists of many steps. An AI assistant within the interface gives you hints on how to implement the individual steps, and does not create the workflows on its own.

Regarding costs, note that although n8n itself is free, connecting external services costs money. With OpenAI, prices depend on the model. Therefore, choose smaller, cheaper models if they are sufficient for your purpose. With self-hosting, limits on executions do not apply, but you take on responsibility for the server and security.

For your start, a few proven rules apply: Begin with simple processes such as "form to email" before you build complex agent logic, since errors in large workflows are harder to find. Set up credentials centrally at the beginning so that you do not have to re-enter them at every step. And use the community building blocks, as there are hundreds of ready-made solutions.

Step 11: Placing n8n in Comparison and Starting a Mini Challenge

Compared to Zapier, n8n is designed to be less comfortable for getting started, but it is more flexible and cheaper at larger volumes. Make is well suited for complex logic, but is proprietary. n8n scores with open source, self-hosting, and the ability to integrate AI models such as GPT, Hugging Face, or Stable Diffusion. In addition, you can build your own nodes and add your own API connections.

If you want to get started right away, try out the small challenge: Install n8n locally or sign up in the cloud. Build a workflow that automatically saves new emails in Google Sheets. This way you get a feel for handling, focal points, and possible stumbling blocks.

Summary ??? n8n in the Practical Check: Self-Hosting Open-Source Automation for Free

n8n is a flexible open-source platform for automations that you can run yourself for free or use as a cloud solution. You have full control over data and workflows, benefit from over 500 integrations and almost 5,000 templates, and can integrate AI models directly. Costs arise mainly from servers, cloud subscriptions, and external services. Start with simple processes, use the community, and build larger automations step by step.
