n8n

**n8n: Fair-Code Workflow Automation** **Overview** n8n (nodemation) is a workflow automation tool similar to Zapier or Make, but with a key difference: it is **source-available** and self-hostable. **Key Differentiators** **1. Self-Hostable** You can run n8n on your own server (Docker) for free. - **Privacy**: Data never leaves your infrastructure (GDPR/HIPAA compliance). - **Cost**: No "per-task" fees. You are limited only by your server CPU. **2. Node-Based UI** Visual flowchart interface. - **Start Node**: Webhook, Cron, Event. - **Action Nodes**: HTTP Request, Google Sheets, Slack, OpenAI. **3. Developer Friendly** In any node, you can write JavaScript. - Access data: `items[0].json.myField` - Transform data: `return items.map(i => { newKey: i.json.oldKey })` **Use Cases** - **Internal Tooling**: Sync DB to Spreadsheet. - **Webhooks**: Receive data from Stripe, process it, send to Slack. - **AI Agents**: n8n has strong LangChain integration for building AI pipelines visually. **Licensing** "Fair Code" license. Free for internal business use. You only pay if you sell n8n as a service (e.g., you build a competing Zapier clone). n8n is the top choice for technical teams who want the speed of no-code with the control of self-hosting.
