Apa Itu n8n?
n8n (baca: "n-eight-n") adalah open-source workflow automation tool yang memungkinkan Anda connect different applications dan services untuk automate tasks tanpa coding.
Core Concept:
Instead dari writing code, Anda create workflows dengan connecting "nodes" - setiap node represents action atau trigger dari aplikasi atau service.
Example Workflow:
- Node 1: When new email arrives di Gmail (Trigger)
- Node 2: Extract email address dan subject
- Node 3: Add row ke Google Sheet dengan data tersebut
- Node 4: Send Slack notification ke sales team
All happens automatically, tanpa human intervention.

- Self-hosted version = unlimited workflows
- Unlimited executions
- Scale sesuai kebutuhan
3. 500+ Integrations
