n8n

Overview

n8n is a low-code automation framework that connects various digital services, triggering sophisticated workflows via visual programming. The vault covers n8n as the orchestration layer for AI agents, the self-hosting setup via Coolify, and production deployment workflows.

Key Concepts

• Low-Code Workflow Automation: Drag-and-drop visual builder for connecting webhooks, APIs, AI models, databases, and messaging platforms — minimizing the need for heavy coding.
• Self-Hosted Affordability: Running n8n on managed cloud plans can be costly. Self-hosting through Coolify on a VPS (Hostinger or Hetzner) dramatically slashes costs while avoiding tier limits.
• AI Agent Orchestration: Acts as the message-routing layer for WhatsApp/Instagram AI agents — receives webhooks from Meta, triggers AI processing via HTTP nodes, stores responses, and relays replies back to the client.
• Production-Ready Triggers: Supports HTTP webhooks, cron schedules, and manual triggers for building persistent 24/7 automation pipelines.
• Database & API Integration: Native connectors for Postgres/SQLite, Supabase, Meta APIs, OpenRouter, and any REST endpoint.
