fagoon-upgrade 2.0.3

Fagoon AI Agents Workflow

Fagoon Upgrade

Self-hosted AI platform with workflow automation, agents, chat, and API generation.

Build AI workflows visually, publish them as REST APIs, deploy agents, and chat with LLMs — all running on your own machine.

---

Quick Start

Prerequisites

• Docker Desktop — Download here
• Python 3.10+ — Download here
• pipx (recommended) — Install with: pip install pipx

Install & Run

# Install the CLI
pipx install fagoon-upgrade

# Start the platform
fagoon up

On first run, you'll see a setup wizard:

  Welcome to Fagoon!
  Let's set up your AI platform.

  How would you like to power your AI?
  1) I have an API key (OpenAI, Gemini, Groq, etc.)
  2) Use local Ollama model (free, runs on your machine)
  3) Skip for now (configure later in the UI)

  Choose [1/2/3]:

Pick your option and Fagoon starts automatically.

Access the Platform

Service	URL
Frontend	http://localhost:3000
Backend	http://localhost:8000

Features

Visual Workflow Builder

Drag-and-drop workflow canvas to build AI automations. Connect LLM nodes, filters, loops, and integrations visually.

Workflow-as-API

Publish any workflow as a REST API endpoint with one click. Get an API key and endpoint URL — call it from any app, any language.

curl -X POST https://your-domain/api/v1/workflow-api/my-workflow/execute \
  -H "X-API-Key: wfapi_xxxxx" \
  -H "Content-Type: application/json" \
  -d '{"input": "Summarize this document"}'

AI Agents

Build and deploy conversational AI agents with memory, tool use, and multi-turn conversations.

Chat Interface

Chat with any LLM provider (OpenAI, Gemini, Groq, Anthropic, Ollama) through a unified interface.

Multi-Provider Support

Use any combination of LLM providers. Switch between them per workflow or per agent.

CLI Commands

fagoon up                    # Start the platform (lite mode)
fagoon up --full             # Start with Redis + Celery (multi-worker)
fagoon up --ollama           # Start with local Ollama LLM
fagoon down                  # Stop the platform
fagoon logs -f               # Follow live logs
fagoon status                # Check if running
fagoon update                # Pull latest version and restart
fagoon config set KEY=VALUE  # Set configuration
fagoon config show           # Show current config
fagoon db set-url URL        # Switch database

---

Configuration

Configuration is stored in ~/.fagoon/config.json. Set values via CLI or the web UI.

LLM Provider Keys

fagoon config set GEMINI_API_KEY=your-key-here
fagoon config set OPENAI_API_KEY=your-key-here
fagoon config set GROQ_API_KEY=your-key-here

Or configure through the web UI at http://localhost:3000 after login.

Using Local Ollama

Run with the Ollama profile to use free local models:

fagoon up --ollama

This starts an Ollama container alongside Fagoon. The Gemma 2B model is available as a fallback when no API keys are configured.

---

Deployment Modes

Lite Mode (Default)

Single-user, single-process. No Redis or Celery required. Perfect for personal use and small teams.

fagoon up

Full Mode

Multi-worker with Redis and Celery for background task processing. For production deployments and teams.

fagoon up --full

---

Using Docker Compose Directly

Workflow API — Turn Any Workflow Into an API

1. Build a Workflow

Open http://localhost:3000, create a workflow in the visual canvas.

2. Publish as API

Click API Integration → Generate API Key & Slug. Copy the API key (shown only once).

3. Call It From Anywhere

cURL:

curl -X POST http://localhost:8000/api/v1/workflow-api/your-slug/execute \
  -H "X-API-Key: wfapi_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"input": "Hello from my app"}'

JavaScript:

const response = await fetch('http://localhost:8000/api/v1/workflow-api/your-slug/execute', {
  method: 'POST',
  headers: {
    'X-API-Key': 'wfapi_your_key_here',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ input: 'Hello from my app' })
});
const data = await response.json();
console.log(data.output);

Python:

import requests

response = requests.post(
    'http://localhost:8000/api/v1/workflow-api/your-slug/execute',
    headers={'X-API-Key': 'wfapi_your_key_here'},
    json={'input': 'Hello from my app'}
)
print(response.json()['output'])

API Response Format

{
  "success": true,
  "execution_id": "uuid",
  "status": "COMPLETED",
  "output": {
    "output_text": "AI generated response here",
    "model": "gemini-2.5-flash",
    "usage": { "input_tokens": 100, "output_tokens": 50 }
  },
  "usage": { "duration_ms": 2500 }
}

Troubleshooting

"Cannot connect to Docker daemon"

Start Docker Desktop and wait for the whale icon to appear in your menu bar.

"Port 3000/8000 already in use"

Stop any other services on those ports, or change ports in the compose file.

Platform won't start

fagoon logs -f     # Check logs for errors
fagoon down        # Stop everything
fagoon up          # Restart

Reset everything

fagoon down
docker volume rm fagoon_db fagoon_data   # Removes all data
fagoon up
