Self Hosted Matrix Server: A Comprehensive Guide for Devs

Dear Dev, are you tired of relying on third-party chat applications? Do you want complete control over your communication data? If yes, then a self-hosted Matrix server is just what you need! In this article, we will guide you through the process of setting up and using a self-hosted Matrix server. Let’s dive in!

What is a Self-Hosted Matrix Server?

A Matrix server is an open-source communication protocol that enables real-time messaging, voice, and video calls. It is decentralized and secure, meaning that your communication data is not stored on a central server owned by a third-party. A self-hosted Matrix server means that you can host your own server on your own device, giving you full control over your data.

How Does Matrix Server Work?

Matrix servers use a federated approach, meaning that users on different servers can communicate with each other as long as their servers are part of the same federation. Each federation has a globally unique identifier (GUID) that allows users to find each other easily. Matrix servers use end-to-end encryption, which means that only the intended recipient can read the message.

Why Should You Use a Self-Hosted Matrix Server?

Self-hosted Matrix servers offer several benefits:

  1. Full control over your data
  2. Privacy and security
  3. No reliance on third-party services
  4. Flexibility to customize your server
  5. No limitations on the number of users or messages

Setting up a Self-Hosted Matrix Server

Step 1: Choose Your Server

The first step in setting up a self-hosted Matrix server is to choose the device that will host your server. This can be a personal computer, a virtual machine, or a dedicated server. Make sure that the device meets the minimum system requirements for a Matrix server.

Step 2: Install the Matrix Server Software

The next step is to install the Matrix server software on your chosen device. There are several Matrix server software options available, including Synapse, Dendrite, and Conduit. For this guide, we will use the Synapse server software.

Step 3: Configure Your Server

Once you have installed the Synapse server software, the next step is to configure your server. This involves setting up a domain name, configuring SSL encryption, and creating an administrator account. You will also need to set up your federation settings to enable communication with other Matrix servers.

Step 4: Invite Users to Your Server

Now that your server is up and running, you can invite users to join your server. You can either create user accounts manually or enable self-registration for your users. You can also create rooms, groups, and channels to organize your communication.

Using a Self-Hosted Matrix Server

Accessing Your Server

To access your Matrix server, you will need a Matrix client. There are several Matrix clients available, including Riot, FluffyChat, and Fractal. Once you have installed a Matrix client, you can log in to your server using your username and password.

Joining Rooms and Groups

Matrix servers support public and private rooms and groups. You can join a public room by searching for it in the Matrix client or by using a room link. To join a private room or group, you will need an invitation from the room or group administrator.

Chatting and Calling

Once you have joined a room or group, you can chat, voice call, or video call with other members. Matrix servers support end-to-end encryption, meaning that only the intended recipient can read the message or participate in the call.


What are the System Requirements for a Matrix Server?

The system requirements for a Matrix server depend on the number of users and messages you expect to handle. As a general rule, you will need at least 2GB of RAM and 4 CPU cores for a small Matrix server. For larger servers, you will need more resources. Consult the documentation for your chosen Matrix server software for specific requirements.

Can I Host Multiple Matrix Servers?

Yes, you can host multiple Matrix servers on different devices and federate them to create a larger network. However, this will require additional configuration and coordination between the servers.

Is Matrix Server Secure?

Yes, Matrix servers are secure. They use end-to-end encryption and support SSL encryption for communication between servers. However, as with any communication service, the security of your Matrix server depends on how you configure it and how you use it.

Can I Customize My Matrix Server?

Yes, you can customize your Matrix server to suit your needs. This includes changing the server settings, adding plugins, and modifying the user interface. However, be careful when modifying the server software, as this can affect its stability and security.

Can I Use a Self-Hosted Matrix Server for Business?

Yes, you can use a self-hosted Matrix server for business communication. Matrix servers offer several advantages over traditional communication services, including privacy, security, and control over your data. However, before using a Matrix server for business communication, consult your organization’s IT policies and regulations.


Setting up and using a self-hosted Matrix server is not as complicated as it seems. With the right tools and guidance, you can have your own secure and private communication network in no time.
