purpose: AI-powered n8n workflow creation with Super Code node specialization type: CLI tool for workflow automation language: TypeScript/JavaScript dependencies: Bun, n8n, AI providers (OpenAI/Anthropic) last-updated: 2025-08-16

AI-powered n8n workflow creation agent, built for the terminal.

Transform your n8n workflow building from manual node configuration to natural language descriptions. Built by Ken Kai who specializes in AI automation.

What This Does

ken8n-coder bridges the gap between natural language workflow descriptions and production-ready n8n automations. Instead of manually configuring nodes and connections, you describe what you want in plain English and get working JavaScript code for n8n's Super Code nodes.

Perfect for:

• Automation engineers building complex JavaScript-based workflows
• Teams standardizing on AI-assisted workflow development
• Rapid prototyping of automation ideas

Quick Start

# Install globally via npm (works on Windows, Mac, and Linux)
npm i -g ken8n-coder@latest

# Launch the terminal interface
ken8n-coder

Terminal-based AI agent that generates n8n workflows with specialized focus on Super Code node JavaScript development. Supports 46+ pre-loaded libraries and multiple AI providers for comprehensive workflow automation.

Core Features

Feature	Description	Benefit
Super Code Specialization	Optimized for n8n's Super Code node with 46+ JavaScript libraries	Generate complex automation logic without manual library management
Multi-Provider AI	OpenAI, Anthropic Claude, and other models	Choose the best AI for your workflow complexity
Terminal TUI	Clean, keyboard-driven interface	Stay in your development flow without context switching
Rapid Iteration	Generate, test, and refine workflows quickly	Accelerate development from idea to production
Library-Rich Environment	Pre-loaded with utilities, data processing, crypto, and more	Build sophisticated workflows without dependency management

Interactive Commands

Start creating a new n8n workflow Launches workflow creation dialog with AI assistance Manage and resume previous workflow sessions View, load, or delete saved workflow development sessions Configure AI model providers and settings Switch between OpenAI, Anthropic, or other supported providers Exit the ken8n-coder interface Safely close the application with session preservation

Super Code Node Libraries

ken8n-coder specializes in generating JavaScript for n8n's Super Code node environment with these pre-loaded libraries:

lodash, axios, cheerio, dayjs, moment, uuid, nanoid, bytes joi/Joi, validator, Ajv, yup, csvParse, papaparse/Papa, xml2js, XMLParser, YAML, ini, toml, qs Handlebars, stringSimilarity, slug, pluralize, fuzzy CryptoJS, forge, jwt, bcrypt, bcryptjs XLSX, pdfLib, archiver, Jimp, QRCode FormData, phoneNumber, iban ethers, web3 ytdl, ffmpeg, ffmpegStatic

Installation

Install ken8n-coder globally using npm. This universal method works on Windows, Mac, and Linux:

# Install with npm (recommended)
npm i -g ken8n-coder@latest

# Alternative package managers also work
bun add -g ken8n-coder@latest
pnpm add -g ken8n-coder@latest
yarn global add ken8n-coder@latest

```bash

Launch ken8n-coder

ken8n-coder

In the TUI

/new

Import into your n8n instance

</pattern>

<pattern name="session-management">

```bash
# Save current work
/sessions

# Resume previous session
/sessions

# Select from list of saved sessions

# Continue iterating on workflow

Examples

Data Processing Workflow

Input: "Process CSV uploads, validate email fields with joi, transform data using lodash, and export to XLSX"

Output: Complete n8n workflow with Super Code nodes containing:
- CSV parsing with papaparse
- Email validation with joi
- Data transformation with lodash utilities

API Integration Workflow

Input: "Fetch data from REST API, handle authentication with JWT, process responses, and store in database"

Output: n8n workflow featuring:
- axios HTTP client configuration
- JWT token handling
- Data validation and processing

Notification System

Input: "Monitor webhook for events, filter based on criteria, format messages with templates, send via multiple channels"

Output: Workflow with:
- Webhook trigger configuration
- Event filtering logic
- Handlebars template processing
- Multi-channel notification delivery

Configuration

ken8n-coder uses a configuration file at ken8n-coder.json:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "context7": {
      "type": "remote",
      "url": "https://mcp.context7.com/sse"
    }
  }
}
