Quick Start
docker run -it --rm -p 5678:5678 n8nio/n8n
# Open http://localhost:5678
Example workflow: GitHub Issue → Slack notification → Google Sheet log
- Add GitHub Trigger node (on new issue)
- Add Slack node (send message to #dev channel)
- Add Google Sheets node (log issue details)
- Activate → runs automatically
Why Developers Switch from Zapier
Zapier charges per task and has no code option:
- Unlimited tasks — self-hosted, no per-execution pricing
- Code nodes — JavaScript/Python for complex logic
- Self-hosted — your data stays on your server
- 400+ integrations — same breadth as Zapier
A startup paid $50/month for Zapier (2,000 tasks). After self-hosted n8n: unlimited tasks, same integrations, $0/month on existing server.
