🚀 Fuse - Workflow Automation

Fuse is a powerful local-first workflow automation platform with visual builder, AI integration, and extensive node library. Build complex automations with a drag-and-drop interface, similar to n8n and Zapier, but optimized for local deployment and AI-powered workflows.

"Keep your workflows in constant fuse" ⚡

✨ Features

🎨 Visual Workflow Builder

• Drag-and-drop interface powered by React Flow
• Real-time workflow execution with live log streaming
• Support for parallel execution, loops, and conditional branching
• 29+ pre-built nodes including triggers, actions, AI, and logic nodes

🤖 AI-Powered Automation

• Built-in AI LLM nodes supporting OpenAI, Anthropic, and Google AI
• AI Agent nodes for autonomous task completion
• AI-assisted workflow generation from natural language prompts
• Token usage tracking and cost monitoring

🔌 Extensive Integration Library

• Triggers: Manual, Cron, Webhook, Email, Form, RSS, WhatsApp
• Actions: HTTP requests, Google Sheets, Slack, Discord, Email
• Logic: Conditions, Switch/Case, Loops, Merge, Delay, Pause
• Data: Transform, Store, Set Variables
• Code: Python and JavaScript execution nodes

🔒 Security & Performance

• JWT-based authentication with secure session management
• Rate limiting and circuit breaker patterns for external API calls
• PostgreSQL database with Alembic migrations
• Redis for caching and Celery task queue
• WebSocket support for real-time updates

📦 Installation

Quick Start

pip install fuse-io

Initialize and Start

# Initialize configuration
fuse init

# Start the server and builder

cd fuse

# Backend setup
cd fuse_backend
pip install -e ".[dev]"

# Frontend setup
cd ../fuse_frontend
npm install
npm run dev

Environment Configuration

Create a .env file in the fuse_backend directory:

# Database
DATABASE_URL=postgresql://user:password@localhost:5432/fuse

# Redis
REDIS_URL=redis://localhost:6379/0

# Security
SECRET_KEY=your-secret-key-change-in-production

# AI API Keys (Optional)
OPENAI_API_KEY=sk-...
ANTHROPIC_API_KEY=sk-ant-...
GOOGLE_API_KEY=AIza...

# OAuth (Optional)
GOOGLE_OAUTH_CLIENT_ID=...
GOOGLE_OAUTH_CLIENT_SECRET=...
SLACK_OAUTH_CLIENT_ID=...
SLACK_OAUTH_CLIENT_SECRET=...

Run with Docker

docker-compose up --build

Access the application at http://localhost:8000

📚 Usage Examples

Creating Your First Workflow

1. Add a Trigger: Start with a Manual Trigger, Webhook, or Cron Schedule
2. Add Actions: Connect HTTP Request, Google Sheets, or AI nodes
3. Add Logic: Use conditions, loops, or parallel branches
4. Test & Deploy: Click "Execute" to test, then activate for production

Example: AIowered Data Processing

# Workflow structure:
# Trigger (Manual) → HTTP Request → AI LLM → Transform → Google Sheets

1. Fetch data from an API
2. Process with AI (summarize, classify, extract)
3. Transform the results
4. Save to Google Sheets

Example: Scheduled Report Generation

# Workflow structure:
# Cron Trigger → Read Sheets → Loop → AI Agent → Email

1. Run daily at 9 AM
2. Read data from Google Sheets
3. Loop through each row
4. Generate insights with AI
5. Send email report

🔐 Security Best Practices

1. Change default SECRET_KEY in production
2. Use environment variables for sensitive data
3. Enable rate limiting for public endpoints
4. Use HTTPS in production deployments
5. Regularly rotate API keys and credentials
