Moltbot on DigitalOcean

​

Goal

​

Cost Comparison (2026)

• DigitalOcean: simplest UX + predictable setup (this guide)
• Hetzner: good price/perf (see Hetzner guide)
• Oracle Cloud: can be $0/month, but is more finicky and ARM-only (see Oracle guide)

​

Prerequisites

• DigitalOcean account (signup with $200 free credit)
• SSH key pair (or willingness to use password auth)
• ~20 minutes

​

1) Create a Droplet

1. Log into DigitalOcean
2. Click Create → Droplets
3. Choose:
   • Region: Closest to you (or your users)
   • Image: Ubuntu 24.04 LTS
   • Size: Basic → Regular → $6/mo (1 vCPU, 1GB RAM, 25GB SSD)
   • Authentication: SSH key (recommended) or password
4. Click Create Droplet
5. Note the IP address

​

2) Connect via SSH

ssh root@YOUR_DROPLET_IP

​

3) Install Moltbot

# Update system
apt update && apt upgrade -y

# Install Node.js 22
curl -fsSL https://deb.nodesource.com/setup_22.x | bash -
apt install -y nodejs

# Install Moltbot
curl -fsSL https://molt.bot/install.sh | bash

# Verify
moltbot --version

​

4) Run Onboarding

moltbot onboard --install-daemon

• Model auth (API keys or OAuth)
• Channel setup (Telegram, WhatsApp, Discord, etc.)
• Gateway token (auto-generated)
• Daemon installation (systemd)

​

5) Verify the Gateway

# Check status
moltbot status

# Check service
systemctl --user status moltbot-gateway.service

# View logs
journalctl --user -u moltbot-gateway.service -f

​

6) Access the Dashboard

# From your local machine
ssh -L 18789:localhost:18789 root@YOUR_DROPLET_IP

# Then open: http://localhost:18789

# On the droplet
curl -fsSL https://tailscale.com/install.sh | sh
tailscale up

# Configure Gateway to use Tailscale Serve
moltbot config set gateway.tailscale.mode serve
moltbot gateway restart

• Serve keeps the Gateway loopback-only and authenticates via Tailscale identity headers.
• To require token/password instead, set gateway.auth.allowTailscale: false or use gateway.auth.mode: "password".

moltbot config set gateway.bind tailnet
moltbot gateway restart

​

7) Connect Your Channels

​

Telegram

moltbot pairing list telegram
moltbot pairing approve telegram <CODE>

​

WhatsApp

moltbot channels login whatsapp
# Scan QR code

​

Optimizations for 1GB RAM

​

Add swap (recommended)

fallocate -l 2G /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
echo '/swapfile none swap sw 0 0' >> /etc/fstab

​

Use a lighter model

• Using API-based models (Claude, GPT) instead of local models
• Setting agents.defaults.model.primary to a smaller model

​

Monitor memory

free -h
htop

​

Persistence

• ~/.clawdbot/ — config, credentials, session data
• ~/clawd/ — workspace (SOUL.md, memory, etc.)

tar -czvf moltbot-backup.tar.gz ~/.clawdbot ~/clawd

​

Oracle Cloud Free Alternative

• Signup can be finicky (retry if it fails)
• ARM architecture — most things work, but some binaries need ARM builds

​

Troubleshooting

​

Gateway won’t start

moltbot gateway status
moltbot doctor --non-interactive
journalctl -u moltbot --no-pager -n 50

​

Port already in use

lsof -i :18789
kill <PID>

​

Out of memory

# Check memory
free -h

# Add more swap
# Or upgrade to $12/mo droplet (2GB RAM)
