n8n
Open-source workflow automation platform with the best AI-agent implementation of any commercial automation tool (Simon Høiberg’s claim, corroborated by every n8n source in this wiki). Self-hostable for unlimited workflows; SaaS tier exists. The dominant builder’s substrate for the AI-automation-agency category and the canonical visual home for the five high-value automations.
Why it matters
n8n is the convergence point for a huge swath of the wiki’s AI-agent content: voice agents, knowledge-graph memory agents, content repurposing pipelines, business automations. Where claude-code is the canonical AI dev tool, n8n is the canonical no-code agent runner. Long-standing gap in the wiki — finally filled.
Patterns this wiki covers
- AI agent node with chat models from OpenAI, Anthropic, openrouter, etc.
- Webhook triggers for inbound events (voice calls, emails, form submissions)
- HTTP request nodes for arbitrary API integration when native nodes don’t exist
- Code nodes for cleanup/transformation between API responses (Claude can write these from a sample JSON)
- Memory backends: simple in-NodeMem, Postgres for short-term, zep for long-term knowledge graph
- Output parsers with structured output schemas to control LLM JSON shape
Workflows in this wiki
- Inbound voice agent — Retell + n8n + Google Sheets/HubSpot
- YouTube → SEO blog — n8n + YouTube Transcript API + OpenRouter + WordPress
- YouTube channel scraper — free YouTube Data API v3 scraper; foundational creator-research recipe
- n8n + Zep memory — knowledge-graph long-term memory for n8n agents
- 500 AI Workflows — five highest-value automations
- Faceless YouTube Shorts — Ideas Agent + Creator Agent + json-to-video short-form pipeline
- Longform YouTube videos — Jay E’s deeper variant with 3-section error-routed Creator Agent and JSON-template customization
- Perplexity node v1.98+ — first-class real-time search inside the AI Agent node
- n8n + MCP via community node —
n8n-nodes-mcplets n8n consume any MCP server (Brave Search demo) - Self-hostable alternatives — n8n as the Zapier/Make replacement
- AI Agent Business Ideas — selling n8n workflows as templates or webhook APIs
First-class nodes worth tracking
- Perplexity (v1.98+) — real-time web search with citations as a first-class node and AI Agent tool slot. See perplexity.
- Zep — long-term knowledge-graph memory backend
- AI Agent — central node that hosts tools (Perplexity, MCP servers, etc) and routes them through a chosen LLM
Self-hosting
Single Docker container; community edition is full-featured. Hostinger and other VPS providers offer one-click installs (referenced across multiple wiki sources).
