What Is n8n?
n8n (short for “node-to-node”) is an open-source workflow automation tool that allows you to connect applications, APIs, and services to automate complex workflows.
Unlike traditional no-code tools, n8n is designed with technical users in mind, offering:
- Full self-hosting
- Advanced logic and branching
- Native JavaScript support
- Complete data ownership
This makes n8n especially popular among developers, startups, data teams, AI builders, and affiliate marketers.
How n8n Works
n8n uses a visual, node-based workflow editor.
Each workflow typically consists of:
- Trigger nodes – Webhooks, Cron jobs, app events
- Processing nodes – Filters, conditions, loops, transformations
- Action nodes – API calls, database writes, notifications
Example workflows:
- Webhook → Validate data → Save to database → Send Slack alert
- Website crawl → AI analysis → Generate structured JSON → Publish content
- Affiliate feed → Keyword detection → Auto-insert affiliate links
This modular design allows you to build simple automations or highly complex systems.
