Matrix (Synapse backend)

This image contains a database (PostgreSQL), a matrix server (Synapse), a matrix web client (Element Web), and a reverse proxy (Caddy). After walking through the simple setup procedure, you will be able to login to your own Matrix web client and chat on the fediverse!

Creating an App using the API

In addition to creating a Droplet from the Matrix (Synapse backend) 1-Click App using the control panel, you can also use the DigitalOcean API. As an example, to create a 4GB Matrix (Synapse backend) Droplet in the SFO2 region, you can use the following curl command. You need to either save your API access token) to an environment variable or substitute it in the command below.

curl -X POST -H 'Content-Type: application/json' \
         -H 'Authorization: Bearer '$TOKEN'' -d \
        '{"name":"choose_a_name","region":"sfo2","size":"s-2vcpu-4gb","image": "sharklabs-matrixsynapsebac-10"}' \

Hardware Requirements

Keep in mind when selecting a monthly plan that the more resources you can provide, the better the chat quality will be. 2GB+ RAM is highly recommended.


  • A new DNS domain you’d like to use exclusively for Matrix (it is recommended and also very cute to buy a .town, .space, or similar domain for this purpose)
  • You must be capable of managing the DNS records for the domain you’d like to use
  • openssh (or putty)
  • 5 minutes

  1. Login to your droplet via ssh root@your_droplet_public_ipv4
