n8n - What Is It and How to Automate Processes Without Coding?
How many hours are lost in your company manually retyping data between systems? Research shows that employees waste an average of 20-30 minutes a day copying information between applications. n8n solves this problem: it is an open-source process automation platform that connects applications in a visual editor - without having to write code.
What is n8n and how does it work?
n8n (pronounced: n eight n) is a business process automation tool that combines a visual approach with the ability to deeply customize workflows. The name comes from "node-based automation". n8n connects hundreds of systems - CRMs, spreadsheets, databases, messaging apps, APIs - into a single automated sequence of operations and reduces the risk of human error.
It is a German company: n8n GmbH is headquartered in Berlin, and the project was founded by Jan Oberhauser in 2019. n8n operates on a low-code/no-code model, so automations can be handled both by non-technical people and IT teams extending standard features with custom scripts.
Working in n8n takes place on a visual drag-and-drop canvas where you drag and connect ready-made blocks. n8n offers over 400 prebuilt app integrations, and the list grows with every release - this is one of the pillars of its popularity on the market.
Open source license - is n8n free?
n8n stands out in the market with its fair-code license - an intermediate model between open source and proprietary software. The code is public on GitHub, can be modified and run on your own infrastructure for free, but the company retains the rights to commercial hosting.
Therefore, the deployment cost depends on the chosen model. The Community Edition is free, with no limits on the number of workflows and executions. The fully managed n8n Cloud and the Business and Enterprise plans remain paid, billed from August 2025 based on the number of executions rather than the number of workflows.
A practical benefit is the absence of vendor lock-in: you can migrate a self-hosted installation between environments at any time. Proprietary SaaS platforms do not allow this, which is why n8n is often a natural choice for companies scaling their processes.
n8n self-hosted vs n8n Cloud
The choice comes down to a decision between full control and the convenience of a ready-made environment. The n8n deployment model directly affects the total cost of the project.
Companies in the financial or medical sectors more frequently choose self-hosted installations because the data never leaves their local infrastructure. Teams that want to deploy automation right away turn to n8n Cloud and pay proportionally to the scale of their operations.
A common practice is to start on your own server during the prototyping phase and then migrate the verified processes to a managed environment - without rewriting the logic from scratch.

n8n vs Zapier vs Make
Zapier and Make dominate in the number of integrations, but they operate exclusively as proprietary SaaS platforms. n8n offers a third path: a free self-hosted edition with no limits and flexible billing in n8n Cloud.
The difference in the number of integrations loses significance in practice - n8n connects to any API via the HTTP Request node, and custom scripts build logic unavailable in competitors' prebuilt modules.
The advantage grows where execution counts surge and data must remain local.
Key features of n8n
The n8n feature set covers both simple and complex automation scenarios:
- Visual editor - building workflows using the drag-and-drop method, without coding.
- Over 400 integrations - prebuilt nodes for popular applications and services.
- Custom nodes - users can create custom nodes in JavaScript.
- Conditional logic - branches and loops handle complex business scenarios.
- Google Sheets automation - reading and writing data directly from a spreadsheet.
The scope of features depends on the deployment scale, but even the free edition provides access to the platform's full capabilities.
Custom scripts in JavaScript and Python
When prebuilt nodes are not enough, n8n lets you add scripts in JavaScript or Python - this is handled by a dedicated Code node, and each such node runs in isolation.
In version 2.x, code executes in isolated task runners (sandboxes), which improves security and speeds up operations by several times. As a result, a single tool can handle both simple automation and advanced data transformation within one workflow.
AI Agent - automation with AI models
n8n offers built-in modules for working with AI models. The AI Agent node integrates large language models (GPT, Claude, local models) that autonomously select tools and make decisions on the fly.
Working with AI models shifts automation from rigid if/else logic toward autonomous scenarios - the agent classifies the ticket on its own and chooses the next path without manually mapping every step of the workflow.
Google Sheets integration
The Google Sheets integration lets you treat a spreadsheet like a full-fledged database - as a data source and a place to save results.
A dedicated node handles reading, appending, and updating rows, enabling two-way synchronization, for example, between a marketing sheet and a CRM within a single workflow.
Access to Google Sheets requires OAuth2 authentication: you create a project in the Google Cloud Console, generate a client ID and secret, and the token refreshes automatically. The same mechanism handles Gmail and Slack, which is why it has become the standard for most deployments.
Data security and GDPR compliance
Self-hosting allows personal data to be processed entirely within the company's infrastructure - customer or employee data does not have to leave a server in the EU, which makes GDPR compliance easier.
n8n also provides enterprise-grade security: full on-premise deployment, SSO login (SAML and LDAP), encrypted secret vaults protecting data, and real-time alerts. Audit logs are available to track workflow history, and the entire setup is ready for production environments.
GDPR compliance also requires several organizational measures, depending on the hosting model: a record of processing activities, minimization of data transferred between nodes, and deliberate retention of execution logs.
Is n8n outdated?
No. n8n remains an actively developed, advanced open-source automation tool. The 2.x line introduced task runners, many times faster code execution, and a steady increase in integrations. Rather than losing relevance, the platform is gaining ground thanks to AI modules that many older tools lack.
For teams planning a long-term deployment, this means a stable foundation that will not force a migration to another solution in the coming years.
User reviews
Users rate n8n at 4/5 for its rich feature set and appreciate the lack of vendor lock-in as well as the free open-source edition. The most commonly cited drawback is the steep learning curve - n8n's flexibility means more concepts to master at the start. For many companies, this entry barrier quickly pays for itself: eliminating 20-30 minutes of daily data copying is a tangible result of automation.
A good practice is to assign one person as the deployment lead - this shortens the learning curve and standardizes how workflows are built across the entire team.
How to get started with n8n?
The best start is a small, single-step workflow - only add further logic once it has stabilized. This sequence in automation prevents error loops and data loss.
- Test installation - Docker spins up the Community Edition environment in minutes, at no cost.
- First trigger - a Manual Trigger or Webhook demonstrates the data flow step by step.
- Error handling - an Error Trigger with a clear stop condition protects against uncontrolled loops.
- Versioning - exporting to JSON in a git repository allows you to revert to verified configurations.
Without these safeguards, complex automation quickly becomes difficult to maintain - their absence is the most common cause of problems in larger deployments.
FAQ
Is n8n a German company?
Yes. n8n GmbH is based in Berlin, and the project was founded in 2019.
Is AI in n8n free?
Yes, the AI Agent node and working with artificial intelligence models also work in the free self-hosted edition. You only pay for calls to the external model directly to its provider.
Do you need to know how to code to use n8n?
No. You build basic automation processes visually using ready-made nodes. Knowledge of JavaScript or Python only comes in handy for advanced data transformation.
