Matrix is an open standard for #decentralized and end-to-end #encrypted #communication. It is a collection of servers and services that communicate with each other using a standardized API that synchronizes in real time. It uses homeservers to store account information and chat history. If one #homeserver goes down, other servers can continue communication without issues due to the nature of decentralization. You can either use a Matrix homeserver hosted by someone else or host your own to maintain control over your data.

In this tutorial, you will learn how to install and create a chat server using Synapse, a homeserver implementation of Matrix. #Element is a #Matrix web client built using Matrix React SDK. This will allow you to offer Matrix chat on the web. You can also use the server using any other Matrix client of your choice. We will also be installing the Coturn server to enable Voice and Video calling. The #Coturn service is optional in case you are not interested in using it.
