n8n Workflow Automation Tutorial 2026

What is n8n?

n8n is open-source workflow automation — think of it as Zapier or Make.com you control. You build automations by connecting "nodes" (triggers, actions, transformations) into flows. Free if self-hosted, paid cloud option available.

n8n vs. Zapier vs. Make

n8n: Open-source, self-hostable, 400+ integrations, code nodes when needed. Best for technical teams or growing automation needs.
Zapier: Easiest UX, 6,000+ apps, expensive at scale ($20+/mo per task volume).
Make.com: Visual flow editor, mid-priced, fewer apps than Zapier.

8 Real n8n Workflows for SMBs

Lead capture: Web form → Slack/LINE notify → CRM entry
AI content generation: Schedule trigger → GPT/Claude API → publish to WordPress/Notion
Customer support routing: Email arrives → AI classify priority → route to right person
Sales pipeline: New customer → enrich data (Apollo/Clearbit) → assign to rep → schedule follow-up
Invoice automation: Stripe payment → generate PDF → email to customer + accountant
Social media auto-post: Schedule trigger → fetch content → post to IG/Twitter/LinkedIn
Competitor monitoring: Daily scrape competitor pages → diff detect → notify if changes
AI-powered research: Topic input → GPT-4 web search → compile report → email/Notion save

Cost Breakdown

Self-hosted (recommended for technical users): $5-10/month VPS + free n8n. DigitalOcean Droplets start at $6/mo — the most reliable option for n8n self-hosting. Use VPS Compare to find cheapest provider.

n8n Cloud: Starter $20/mo, Pro $50/mo, Enterprise custom. Includes hosting, monitoring, backups.

When to Use n8n vs. LINE Bot

n8n is the engine; LINE Bot is the channel. Real setup: LINE Bot receives user message → triggers n8n workflow → n8n does heavy lifting (AI processing, DB lookups, API calls) → returns to LINE Bot → user sees response.

If your business needs LINE-first user interaction, see LINE Bot Complete Guide. For pure backend automation, n8n alone suffices.
