What Is n8n?

The Plain-English Explanation

n8n occupies a unique position between no-code automation platforms like Zapier and full custom development. You build workflows visually by connecting nodes, but you can also write custom JavaScript or Python within any node when you need more control. And because it's open-source, you can self-host it — keeping all your data on your own servers.

n8n has become particularly popular for building AI agent workflows because of its flexibility. You can chain together multiple AI calls, process the results, make decisions, and interact with any API — all within a visual workflow that's easy to understand and modify.

Why It Matters

For technically-minded professionals and teams building AI-powered workflows, n8n offers the best balance of power and accessibility. Self-hosting means complete data privacy. The open-source model means no vendor lock-in. And the combination of no-code and code capabilities means you're never limited by the platform.

Examples in Practice

A development team building an AI code review agent that pulls new pull requests, analyses code with multiple LLMs, generates review comments, and posts them back to GitHub.
A research team creating an automated literature review pipeline that searches databases, downloads papers, extracts key findings with AI, and compiles structured summaries.
A data team building an ETL pipeline that ingests data from multiple sources, uses AI for classification and enrichment, and loads clean data into their warehouse.

Common Misconceptions

Myth: n8n is only for developers.

Reality: While developers get the most out of n8n's code capabilities, the visual workflow builder is accessible to anyone comfortable with logical thinking. Many non-developers build effective n8n workflows.

Myth: Self-hosting is complicated and expensive.

Reality: n8n can run on a $5/month cloud server. Docker deployment takes minutes. n8n also offers a cloud-hosted option for those who prefer not to self-host.

Myth: n8n has fewer integrations than Zapier.

Reality: n8n has 400+ built-in integrations and can connect to any service with an API through its HTTP request node. For many use cases, it connects to the same tools as Zapier.
