VPS for a Discord bot: deployment and hosting

For Discord bot hosting, a VPS with 1-2 vCPU, 1-2 GB RAM, and an NVMe disk is optimal, ensuring stable operation and low latency; such plans start from $5-7/month. Choosing a VPS for a Discord bot is a decision that guarantees reliability, scalability, and full control over the environment, unlike free or limited hosting options. In this article, we will detail how to choose the right VPS for a Discord bot, what server requirements are, and step-by-step deploy a bot using Node.js or Python with systemd to ensure continuous operation.

Why is a VPS the best choice for Discord bot hosting?

When it comes to where to host your Discord bot, several options exist, but a Discord VPS stands out as the most reliable and flexible. Unlike a home computer, which can shut down or experience internet connection issues, or free hosting services with their resource and uptime limitations, a VPS offers dedicated resources and professional data center infrastructure.

• Reliability and Uptime: VPS providers guarantee a high uptime percentage (often 99.9% and higher), which is critical for a bot that needs to be available 24/7.
• Dedicated Resources: Your bot will not compete for CPU, RAM, or disk I/O with other users. All resources specified in your plan are exclusively available to you.
• Full Control: You get root access to the operating system, allowing you to install any libraries, frameworks, and configure the server to meet your bot's specific needs.
• Scalability: As your bot grows and the number of servers or users increases, you can easily upgrade your VPS to a more powerful plan without having to migrate the entire project.
• Security: You control the security settings, can configure a firewall, SSH keys, and other protective measures.

What requirements does a Discord bot have for a VPS?

Choosing the right Discord bot server begins with understanding your bot's requirements. These depend on the programming language, the number of servers the bot operates on, the complexity of commands, and the intensity of external API or database usage.

CPU (Processor)

For most Discord bots, 1-2 vCPUs are sufficient. Bots are rarely CPU-intensive unless they perform complex calculations, image processing, or video processing. Python bots, especially asynchronous ones, can efficiently utilize a single core, while Node.js bots, thanks to their non-blocking nature, also perform well with a limited number of cores.

RAM (Random Access Memory)

RAM is one of the most important resources for Discord bot hosting. The amount of RAM required directly depends on:

• Number of Discord servers: The more servers, the more user, channel, and message data the bot needs to store in memory.
• Libraries used: Some libraries can be more resource-intensive.
• Bot functionality: If the bot caches large amounts of data, works with databases (even in-memory), processes files, or performs complex operations, it will require more RAM.

Approximate requirements:

• Small bot (up to 500 users, 1-10 servers): 512 MB - 1 GB RAM.
• Medium bot (up to 5000 users, 10-50 servers): 2 GB RAM.
• Large bot (over 5000 users, 50+ servers): 4 GB RAM and above. Very large bots with sharding may require 8 GB RAM or more.

Disk Space and Disk Type

For bot code, logs, and a small database, 10-20 GB of disk space is usually sufficient. However, the disk type significantly impacts performance. We strongly recommend using NVMe disks. They provide significantly higher read/write speeds compared to traditional SSDs or HDDs, which speeds up bot startup, database operations, and module loading. You can learn more about the advantages of NVMe in our article: NVMe vs SSD vs HDD: Which Disk to Choose for a Server.

Network Bandwidth

Discord bots do not consume much traffic unless they are transferring large files or streaming audio/video. Typically, 500 GB - 1 TB of monthly traffic is more than enough for most bots. Network stability and low latency are more important.

Choosing an Operating System and VPS Location

For a VPS for a Discord bot, the most common choice is Linux distributions like Ubuntu Server or Debian. They are lightweight, stable, and well-documented. Versions without a graphical interface (CLI-only) consume fewer resources.

The VPS location can also be important. If most of your users are in a specific region, choosing a VPS in the nearest data center can reduce latency. For example, for a European audience, data centers in Germany, France, or the Netherlands would be suitable. Valebyte offers a wide selection of locations worldwide.

Deploying a Discord Bot on a VPS (Node.js/Python)

Let's consider a step-by-step process for deploying a bot using Ubuntu Server as an example.

1. Connecting to the VPS and Initial Setup

Connect to your VPS via SSH. Replace your_user and your_vps_ip with your own details:

ssh your_user@your_vps_ip

Update the system:

sudo apt update && sudo apt upgrade -y

Configure a basic firewall (ufw), allowing SSH access:

sudo apt install ufw -y
sudo ufw allow OpenSSH
sudo ufw enable
sudo ufw status

2. Installing Node.js or Python

For Node.js bots:

Use nvm (Node Version Manager) for flexible Node.js installation:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
source ~/.bashrc
nvm install node # Installs the latest LTS version
nvm use node

Verify the installation:

node -v
npm -v

For Python bots:

Python 3 is usually pre-installed. It is recommended to use venv for dependency isolation:

sudo apt install python3-pip python3-venv -y
python3 -m venv ~/mybot_venv
source ~/mybot_venv/bin/activate

3. Uploading the Bot Code

Clone your bot's repository:

git clone https://github.com/your-username/your-discord-bot.git
cd your-discord-bot

Install dependencies:

For Node.js:

npm install

For Python:

pip install -r requirements.txt

Create an .env file or configure environment variables with your Discord token and other sensitive data. Never store your token directly in the code or in a public repository!

4. Configuring Systemd for Continuous Operation

systemd is a Linux system and service manager that ensures your bot starts when the server boots and automatically restarts in case of failures. This is a key component of reliable Discord bot hosting.

Create a service file. Replace your_user, /path/to/your-discord-bot, and bot_entry_file.js/bot_entry_file.py with your own details:

sudo nano /etc/systemd/system/discord-bot.service

Content for a Node.js bot:

[Unit]
Description=My Discord Bot
After=network.target

[Service]
User=your_user
WorkingDirectory=/path/to/your-discord-bot
ExecStart=/home/your_user/.nvm/versions/node/vYOUR_NODE_VERSION/bin/node bot_entry_file.js
Restart=always
RestartSec=5
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=discord-bot

[Install]
WantedBy=multi-user.target

Content for a Python bot (with venv):

[Unit]
Description=My Discord Bot
After=network.target

[Service]
User=your_user
WorkingDirectory=/path/to/your-discord-bot
ExecStart=/home/your_user/mybot_venv/bin/python bot_entry_file.py
Restart=always
RestartSec=5
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=discord-bot

[Install]
WantedBy=multi-user.target

Save and close the file (Ctrl+X, Y, Enter). Reload systemd so it recognizes the new service:

sudo systemctl daemon-reload

Start the bot and enable autostart on system boot:

sudo systemctl start discord-bot
sudo systemctl enable discord-bot

Check the bot's status:

sudo systemctl status discord-bot

You can also view the bot's logs:

sudo journalctl -u discord-bot -f

Monitoring and Maintaining a Discord Bot on a VPS

Even after successful deployment, it's important to regularly monitor the status of your Discord bot server and the bot itself. This will help you promptly identify and resolve issues, as well as plan for scaling.

• Check service status: sudo systemctl status discord-bot
• View logs: sudo journalctl -u discord-bot -f
• Resource monitoring: Use htop to track CPU and RAM, free -h for RAM, df -h for disk space.
• Configure notifications: For more advanced monitoring, you can set up a notification system for bot crashes or exceeding resource thresholds. Solutions like Prometheus and Grafana, or Zabbix, are excellent for this. You can read more about this in our article: Monitoring Server: Zabbix, Prometheus, Grafana.

Don't forget to regularly update your bot's dependencies and the operating system to maintain security and stability.
