How to Use

Method 1: Direct Binary Execution

1. Configure environment variables

   Create a .env file or set environment variables:

   export API_TOKEN=your_token_here
   export DATABASE_URL=your_database_url_here  # e.g., postgres://user:pass@host:port/dbname
   export PORT=8080  # Optional, defaults to 8080

2. Start the Snell Panel server

   ./snell-panel

Method 2: Using Docker Compose (Recommended)

1. Configure the compose.yaml file

   Edit the compose.yaml file and update the environment variables:

   environment:
     - API_TOKEN=your_token_here
     - DATABASE_URL=your_database_url_here

2. Start the service

   docker-compose up -d

   The service will be available on port 9997.

Method 3: Using Docker

1. Build the Docker image

   docker build -t snell-panel .

2. Run the container

   docker run -d \
     --name snell-panel \
     -p 8080:8080 \
     -e API_TOKEN=your_token_here \
     -e DATABASE_URL=your_database_url_here \
     snell-panel

Method 4: Vercel Serverless Deployment

1. Set up Supabase Database

   • Go to supabase.com and create a new project
   • Navigate to Settings > Database and copy the connection string
   • The connection string format should be: postgresql://postgres:[YOUR-PASSWORD]@[YOUR-HOST]:[YOUR-PORT]/postgres

   Detailed Steps:

   • Create a Supabase account and new project
   • Go to Project Settings → Database
   • Under "Connection string", select "URI"
   • Copy the connection string (it will look like postgresql://postgres:[YOUR-PASSWORD]@db.xxxxx.supabase.co:5432/postgres)
   • Replace [YOUR-PASSWORD] with your actual database password

2. Deploy to Vercel

   Click the button below to deploy directly to Vercel:

   

   Or manually deploy:

   # Clone the repository
   git clone https://github.com/missuo/snell-panel.git
   cd snell-panel
   
   # Install Vercel CLI
   npm i -g vercel
   
   # Deploy to Vercel
   vercel --prod

3. Configure Environment Variables in Vercel

   In your Vercel dashboard, go to your project settings and add the following environment variables:

   API_TOKEN=your_token_here
   DATABASE_URL=your_supabase_database_url
   

   Example Supabase DATABASE_URL:

   postgresql://postgres:your_password@db.abcdefghijklmnop.supabase.co:5432/postgres
   

4. Access your deployment

   Your Snell Panel will be available at https://your-project-name.vercel.app

   Advantages of Vercel Deployment:

   • Serverless architecture with automatic scaling
   • Global edge network for faster response times
   • Automatic HTTPS and custom domain support
   • Zero server maintenance required
   • Free tier available for personal projects

Install Snell Server

Use the following command to install Snell Server:

bash <(curl -Ls https://ssa.sx/sn) install your_panel_url your_token custom_node_name

Use the following command to uninstall Snell Server:

bash <(curl -Ls https://ssa.sx/sn) uninstall your_panel_url your_token custom_node_name

custom_node_name is optional. If your node name contains spaces, please use quotes. For example:

bash <(curl -Ls https://ssa.sx/sn) install your_panel_url your_token "My Node Name"

Use the following command to update Snell Server:

bash <(curl -Ls https://ssa.sx/sn) update

Access the Web UI

Access the management Web UI using the following link:

https://snell-panel.owo.nz

Web UI Features:

• Dashboard: Overview of all managed nodes and their status
• Node Management: Add, delete, and configure Snell proxy nodes
• Node Customization: Rename nodes for better organization and identification
• Relay Configuration: Set up sub-nodes (relay/transit nodes) for advanced routing scenarios
• Subscription Links: Generate and copy subscription URLs for various proxy clients
• Real-time Updates: Live status monitoring and configuration changes

You can get the subscription link from the Web UI.

Alternative: iOS App

You can also use the iOS App instead of the WebUI for a better mobile experience. Since the app is not yet available on the App Store, you must use TestFlight to install it:

TestFlight Beta Download: https://testflight.apple.com/join/wKvw64P6

iOS App Features:

• Native Interface: Optimized touch interface for iOS devices
• Full Functionality: Complete node management capabilities matching the Web UI
• Node Operations: Add, delete, rename, and configure nodes on-the-go
• Relay Management: Configure sub-nodes and routing policies
• Subscription Sharing: Easy copy and share subscription links
• Offline Access: View node configurations even when offline

Installation Notes:

• The TestFlight beta may have limited slots available
• You need to install TestFlight first on your iOS device
• The iOS app provides the same functionality as the web interface with native mobile optimization

Web UI Source Code

The Snell Panel project consists of multiple components:

• Backend API Server: Open source (this repository) - Go-based RESTful API server
• Web UI Frontend: Closed source - Browser-based management interface
• iOS App: Closed source - Native iOS application

We are currently not considering open-sourcing the frontend code (Web UI and iOS App) at this time. The backend API server remains fully open source and provides complete programmatic access to all functionality.
