How to Install Synapse on Your Synology NAS

How to Install Synapse on Your Synology NAS

Matrix is an open standard for decentralized communication which securely distributes persistent chatrooms over an open federation of servers, preventing any single points of control or failure. This guide will help you install and get started with Matrix and its reference home server, Synapse. You can install it on a mini-computer like the Raspberry Pi or on a Synology NAS to host Matrix Synapse for your family, friends or company. In this step by step guide I will show you how to install Synapse on your Synology NAS using Docker and Portainer.

💡Note: This guide works perfectly with the latest Synapse v1.98.0 release.
