How to Run Moltbot on a VPS

If you've been running Moltbot on your laptop, you know the problem: close the lid, bot goes offline. Your Discord members wake up to a dead bot because Windows Update decided 3am was the perfect time to restart.

A VPS fixes this. Your bot runs on a server that stays on, in a datacenter with actual redundant power and network connections. No more "sorry guys, my PC crashed" messages in your server.

This guide covers the full setup: picking a VPS, running the installer, and verifying everything works.

Why bother with a VPS?

Running locally works fine for testing, but production Discord bots need something more stable:

• Your bot stays online when your computer is off (obvious, but worth stating)
• Datacenter connections have lower latency to Discord's servers
• You can upgrade RAM or CPU without buying new hardware
• Built-in DDoS protection keeps your bot safe from attacks

The real benefit? Peace of mind. Set it up once, and stop worrying about uptime.

Choosing a VPS

Moltbot doesn't need much. Here's what works:

Resource	Minimum	Recommended
CPU	1 vCore	2 vCores
RAM	1 GB	2 GB
Storage	10 GB SSD	20 GB SSD
Bandwidth	500 GB/month	1 TB/month

If you want something pre-configured, our Moltbot VPS plans come with clean IPs and are already set up for Discord bot hosting.

What you'll need

1. A VPS running Ubuntu 22.04 or newer (our Linux VPS works well)
2. SSH access to your server
3. Your Discord bot token
4. Basic comfort with the command line

Step 1: Connect to your VPS

Open your terminal and SSH in:

ssh root@your-server-ip

Replace your-server-ip with the IP from your VPS welcome email. On Windows? Check our guide on connecting from any device.

Step 2: Install Moltbot

The installer handles everything—Node.js, dependencies, and configuration:

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

Follow the prompts to enter your Discord bot token and configure your preferences. Moltbot runs automatically in the background and starts on boot.

Step 3: Verify it's running

Head over to Discord and confirm your bot appears online in your server. That's it.

Updating Moltbot

Run the installer again to update:

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

It detects existing installations and updates them in place.

Troubleshooting

Bot goes offline randomly

Usually a RAM issue. Check if your system is running low:

free -h

If RAM is consistently above 80%, you need a bigger VPS.

Connection timeouts

Discord has occasional blips. Moltbot reconnects automatically, but you can check your server's network:

ping -c 5 discord.com

Packet loss? See our guide on fixing slow connections.

Permission errors

Make sure the moltbot user owns everything:

sudo chown -R moltbot:moltbot /home/moltbot/moltbot

Security basics

A few things worth doing:

Update your system regularly with apt update && apt upgrade.

Set up a firewall. UFW makes this easy:

sudo ufw allow ssh sudo ufw enable

Switch to SSH key authentication instead of passwords. It's more secure and honestly more convenient.

Keep a backup of your .env file somewhere safe—not on the server, in case you need to rebuild.

What now?

Your bot should be running. A few ideas from here:

Your VPS can run multiple bots—just repeat the process for each one. Set up UptimeRobot or a similar service to alert you if something goes down. Poke around Moltbot's settings to configure moderation and DM pairing.
