In 2019, a German developer named Jan Oberhauser published a project on GitHub that would change how small and large companies think about automation. n8n was born out of real frustration: existing automation tools were too expensive, too limited, or locked your data in servers you didn't control. Three years later, the project had over 40,000 stars on GitHub. By 2026, n8n had established itself as the most versatile automation platform on the market, with over 400 native integrations and a global community that contributes new nodes and templates daily.
But what exactly is n8n? At its core, it's a workflow automation platform based on visual nodes. You connect blocks — each block representing an action, a decision, or an integration — and create flows that execute tasks automatically. Receiving an email, extracting data, processing it with artificial intelligence, saving it to a database, and sending a notification on Slack: all of this can be a single workflow that runs without human intervention.
n8n's differentiator compared to competitors boils down to three pillars. First, it's open-source with a fair-code license. This means you can see every line of code, audit security, contribute improvements, and, most importantly, host the tool on your own server. Your data never needs to leave your infrastructure. Second, the pricing model is radically different: while competitors charge per execution or per task, the self-hosted version of n8n has no execution limits. You only pay for the infrastructure you choose to use. Third, the technical flexibility is unmatched — you can write JavaScript or Python code directly in workflows, connect to any REST API, and create custom nodes for specific needs.
For tech professionals, n8n represents a bridge between the low-code world and traditional development. You don't have to choose between dragging blocks in a visual interface and writing code: n8n allows both, in the same workflow, with the same elegance. For entrepreneurs and managers, it means a single person can automate processes that would previously require an entire team of developers.
The n8n ecosystem in 2026 is robust. The company behind the project raised around 35 million dollars in investment by the end of 2025 (Series A and Series B rounds), maintains a dedicated development team, and operates n8n.cloud as a managed option for those who prefer not to deal with infrastructure. The community has created thousands of ready-made templates, shares workflows on the official forum, and contributes integrations ranging from Brazilian ERPs to cutting-edge AI platforms.
This course was built for those who want to truly master n8n — not just drag blocks, but understand the architecture behind it, build complex automations with artificial intelligence, and turn that knowledge into revenue. Each chapter combines technical foundation with practical application. By the end, you'll have not just the knowledge, but workflows ready to go into production.
What to take away from this chapter:
- n8n is an open-source visual automation platform with over 400 integrations, allowing you to combine a low-code interface with custom code in the same workflow
- The fair-code model allows self-hosting with no execution limits, keeping full control over your data and infrastructure
- The active community and solid company investment ensure constant platform evolution, with new nodes and features in every release
- Automation with n8n isn't just about operational efficiency — it's a monetizable skill that lets individual professionals deliver value equivalent to entire teams
