Matrix has many clients and servers and other projects and finding the right place to ask a question can be difficult.

I originally wanted to contribute this post to official Matrix documentation, but found it too difficult to fit myself into their documentation style guide, so I am typing this into my blog and linking here while hoping for the official Matrix documentation to replace this in the future.

General

The main Matrix room is #matrix:matrix.org, but it’s a little busy and it can be easier to ask in more specific room where you are often directed to. It’s bridged to #matrix at freenode.

Clients

Riot support lives in three rooms depending on your platform:

  • #riot:matrix.org is for Riot Web/Desktop.
  • #riot-android:matrix.org is for Riot Android.
  • #ios:matrix.org is for Riot iOS.

Other rooms exist for other clients:

  • #matrix-ircd:matrix.org for Matrix IRCd, a gateway for IRC clients
    • Replaced PTO.
  • #nachat:matrix.org for NaChat
  • #tensor:matrix.org for Tensor
  • #quaternion:matrix.org for Quaternion (and libqmatrixclient)
  • #weechat:hveem.no for WeeChat matrix.lua script
    • matrix.org address: #weechat:matrix.org
    • Not to be confused with #freenode_#weechat:matrix.org which is for the WeeChat IRC client itself.

And while they are not clients, I think they should be mentioned:

  • #e2e:matrix.org for End-to-end crypto in Matrix
  • #megolm:matrix.org for end-to-end-encryption test
    • Main address not set, so I am using the matrix.org one.

Bridges & Integrations

Room for 3rd party network bridging in general is #bridges:matrix.org which is also bridged to matrix-org/bridging at Gitter. I think some bridges such as Gitter/Slack live there (please correct me if I am wrong!).

The bridges I know to have their own rooms are:

  • #irc:matrix.org for the IRC bridge
  • #twitter:half-shot.uk for the Twitter bridge
    • matrix.org alias #twitter:matrix.org
  • #telematrix:matrix.org for the Telegram bridge
    • Doesn’t have primary address set, so I take the matrix.org one.

Integrations live at #neb:matrix.org which appears to be very little known even to people who have been using Matrix for a long time.

Servers

I haven’t been following server-side so much as I am afraid of the heavy RAM-requirement, but the rooms I am aware of are:

  • #synapse:matrix.org for unofficial Synapse support, but at the time of typing they suggest you to ask questions in #matrix:matrix.org.
  • #ruma:matrix.org for Ruma
