n8n is an open-source workflow automation tool — similar to Zapier or Make, but self-hostable and without per-task pricing. For technical users willing to run their own infrastructure, it is the most powerful option in the workflow automation space.
What n8n Does
n8n connects applications and automates workflows through a visual node-based interface. Each “node” represents an action or trigger (a new email arrives, a form is submitted, a database record changes), and you connect nodes to create sequences: “when a new row is added to this Google Sheet, send a message to this Slack channel and create a task in Linear.” n8n has 350+ built-in integrations: Google Workspace, Slack, GitHub, Notion, Airtable, PostgreSQL, HTTP webhooks, OpenAI, and many more. Anything without a built-in integration can be connected via HTTP request nodes.
n8n vs Zapier vs Make
Zapier: most integrations, easiest to use, per-task pricing that becomes expensive at scale — a workflow running 10,000 times per month costs $50–200+/month. Make: visual, more complex multi-step flows than Zapier, per-operation pricing, hosted only. n8n: self-hosted (free, you pay for the server), fair-code licence, steeper learning curve than both, but unlimited operations on your own server. For developers or technical users who are already running servers: n8n on a $6/month VPS eliminates workflow automation costs entirely.
The AI Integration Story
n8n has built strong AI integration since 2024. The AI Agent node lets you build workflows where an LLM (Claude, OpenAI, Gemini) acts as an agent — processing input, calling tools, making decisions, and generating output — without writing code. This is genuinely powerful for use cases like: email triage and drafting (read emails, classify them, draft responses for review), document processing (extract structured data from PDFs, insert to database), customer support routing (classify inbound messages, route to appropriate queue or generate response). These workflows previously required custom code; n8n makes them buildable visually.
Getting Started
For self-hosting: n8n runs on Docker with a single command, or via the n8n cloud trial for learning before committing to self-hosting. The n8n documentation is excellent. The community forum has workflow templates for the most common use cases. Start with a simple workflow (e.g., “when I receive an email with label X, create a task in my task manager”) and build complexity gradually. Attempting to build complex multi-agent AI workflows on day one is a common beginner mistake.
