Exploring Open-source Live Chat Solutions and a Step-by-Step Guide to Install Rocket.Chat on a VPS

Live chat solutions have become an integral part of online services and businesses. They allow for real-time communication, provide instant support, boost customer engagement, and significantly enhance the user experience. However, the majority of popular live chat solutions are proprietary, often involving subscription fees or compromising user privacy.

Open-source live chat solutions offer a compelling alternative. These self-hosted platforms deliver similar functionalities as their proprietary counterparts like Slack or Microsoft Teams, while also providing added benefits of cost-effectiveness, data control, and customizability. Thanks to their open-source nature, users have the freedom to modify the software to suit their unique requirements.

In this article, we will explore some popular open-source live chat solutions and provide a detailed guide on setting up one of the most widely used open-source chat servers, Rocket.Chat, on a VPS. If you're a small business owner, a privacy-conscious user, or a developer looking to leverage the power of open-source software, this guide is designed for you. So, let's dive right in!

Why Open-Source Live Chat

Open-source live chat solutions are essentially messaging platforms whose source code is openly shared and available for modification. This open availability is transformative, as it allows anyone to study, use, modify, and distribute the software, fostering a collaborative and community-driven approach to software development.

What makes these solutions unique is their self-hosted nature. Instead of relying on a third-party server, businesses can host these platforms on their own servers or a VPS. This results in several key benefits:

  1. Cost-Effective: Open-source solutions generally have no licensing fees, which can significantly reduce costs, especially for small to medium-sized businesses.

  2. Customizable: The flexibility of open-source software allows organizations to tailor these platforms to their specific needs. Whether it's modifying the user interface, integrating with other systems, or developing new functionalities, the possibilities are virtually endless.

  3. Data Control and Privacy: With self-hosting, you have complete control over your data. This is especially important in a world where data privacy and security are increasingly crucial. By hosting the live chat on your own server, your data doesn't leave your controlled environment, reducing the risk of data breaches or third-party access.

A Detailed Guide to Setting Up Rocket.Chat on Your VPS

After thoroughly examining various options, it becomes evident that Rocket.Chat distinguishes itself amidst other open-source live chat solutions. This can be attributed to its comprehensive feature set, user-friendly interface, and consistent active development. Beyond this, Rocket.Chat offers a unique blend of control, customization, and security that makes it an attractive choice for many organizations. Furthermore, the open-source nature of Rocket.Chat enables a level of flexibility and scalability not often found in other platforms. This section will guide you through the process of setting up Rocket.Chat on your VPS, putting you in control of a powerful and flexible communication tool.

Before we start, it's worth noting that this guide assumes you have a VPS running a recent version of Ubuntu (20.04 LTS or later). It also assumes you have SSH access to your VPS and basic familiarity with the command line. Also, please make sure to replace "" with your actual domain name or the IP address of your VPS throughout the guide.

Step 1 - Update your system: Always ensure your system is up-to-date before starting any installation.

sudo apt-get update 
sudo apt-get upgrade

Step2 - Install MongoDB: Rocket.Chat uses MongoDB to store its data.

sudo apt-get install -y mongodb

Step 3 - Install Node.js: Rocket.Chat is built on Node.js, so you'll need to install this as well. We'll use version 12 for compatibility.

curl -fsSL | sudo -E bash - 
sudo apt-get install -y nodejs

Step 4 - Install build tools: These tools are needed to build certain dependencies of Rocket.Chat.

sudo apt-get install -y build-essential

Step 5 - Download Rocket.Chat: Download and extract the latest Rocket.Chat version. Make sure to check the official Rocket.Chat GitHub repository for the latest version.

curl -L -o 
tar zxvf

cd bundle/programs/server 
npm install 
cd ../../..

Step 7 - Set up environment variables: These tell Rocket.Chat where to find the database and what port to run on. You need to add them in /etc/environment to make them persistent.

sudo nano /etc/environment

Add these lines at the end of the file:


Save and close the file.

You can load the environment variables without rebooting by running:

source /etc/environment

Step 8 - Start Rocket.Chat: You can now start Rocket.Chat for the first time to make sure it's working.
