Host a Discord Bot on Hostinger VPS (24/7 Uptime Guide)

Free bot hosting options (Replit, Glitch, free Heroku tiers) have critical limitations:

• Sleep/cold starts: Free services put your bot to sleep after inactivity — it goes offline regularly
• Resource limits: Restricted RAM and CPU cause crashes during busy periods
• No persistent storage: Data lost on container restart
• Unreliable uptime: Free tiers aren't designed for 24/7 operation

A $5/mo Hostinger VPS solves all of these: your bot runs 24/7, has 4GB RAM, persistent disk storage, and 99.97% uptime.

Assuming you have a Discord bot ready (discord.js or discord.py), here's how to deploy it:

# SSH into your Hostinger VPS
ssh root@YOUR_SERVER_IP

# Install Node.js (for discord.js bots)
curl -fsSL https://deb.nodesource.com/setup_20.x | bash -
apt install nodejs -y

# Clone your bot repository
git clone https://github.com/yourusername/your-discord-bot.git
cd your-discord-bot
npm install

# Create environment file
echo "DISCORD_TOKEN=your-bot-token-here" > .env

# Test run
node index.js

If the bot connects and responds, it's working. Now set it up to run permanently.

Option 1: Docker (recommended)

# Create Dockerfile
cat > Dockerfile << 'EOF'
FROM node:20-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci --production
COPY . .
CMD ["node", "index.js"]
EOF

# Create docker-compose.yml
cat > docker-compose.yml << 'EOF'
services:
  bot:
    build: .
    env_file: .env
    restart: unless-stopped
    volumes:
      - ./data:/app/data
EOF

docker compose up -d --build

Option 2: PM2 (simpler)

npm install -g pm2
pm2 start index.js --name discord-bot
pm2 startup  # Auto-start on reboot
pm2 save

Both options ensure your bot restarts automatically after crashes or server reboots.

Make your Discord bot intelligent by adding AI responses:

// Add to your discord.js bot
import Anthropic from '@anthropic-ai/sdk';

const anthropic = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY });

client.on('messageCreate', async (message) => {
  if (message.mentions.has(client.user)) {
    const response = await anthropic.messages.create({
      model: 'claude-sonnet-4-20250514',
      max_tokens: 500,
      messages: [{ role: 'user', content: message.content }]
    });
    message.reply(response.content[0].text);
  }
});

This creates a bot that responds with AI when mentioned. Add conversation history, custom system prompts, and tool use for more sophisticated behavior.
