Look no further, as we have compiled a comprehensive guide on the best self-hosted chat server that is available for free. In this article, we will cover everything you need to know to set up and maintain a self-hosted chat server.

What is a Self-Hosted Chat Server?

A self-hosted chat server is a software application that helps you to create your own chat environment. It’s an alternative to using a third-party chat platform like Facebook, Slack, WhatsApp or any other chat service providers. With self-hosted chat server, you have complete ownership and control over your chat server.

Self-hosted chat servers are free of charge and you can customize them according to your needs. As you’ll be hosting the chat server on your own server, you can also monitor and control the server’s performance, functionality and data security. This helps keep your conversations private and confidential.

How does a Self-Hosted Chat Server Work?

To understand how self-hosted chat server works, let’s first look at the server architecture of a typical chat service provider. A chat service provider typically has a centralized architecture, where all chat messages are stored on their servers. This means that any message sent on the platform has to go through the central server before being delivered to the other party. This architecture can be an issue in case of server downtime or system failures.

However, a self-hosted chat server operates on a decentralized peer-to-peer architecture. The chat messages are directly transmitted from the sender to the receiver’s client devices via the server. This ensures that the server is not required to store messages and the messages are delivered directly, reducing the load on the server and increasing the speed of messaging.

Advantages of Self-Hosted Chat Server

Here are the advantages of using self-hosted chat server for your business or personal use:


Unlike third-party chat service providers, a self-hosted chat server ensures that all messages are stored on your server, making it easy to keep your conversations private and confidential. You can also monitor your server for any potential security breaches or attacks.


A self-hosted chat server can be fully customized to meet your business requirements. You can add new features or modify existing ones to fit your needs. This level of customization is not possible with third-party chat service providers.


Using a self-hosted chat server is cost-effective as it is free to use. You don’t have to pay for any additional features or services. You can also use the server for as long as you like without any recurring costs.


You have complete control over the server and can monitor its performance in real-time. This ensures that you always have access to your chat server, and you can quickly identify and address any issues that arise.
