Unofficial "This Week In Matrix", Take 2

None would write a TWIM post on the last day of the year! None? No, a small independent developer doesn't want to submit to taking time off!

I wish you all a wonderful and happy new year! Because some people are busy on their time off, I collected some of the TWIM entries since the last post a few days ago! Enjoy the read and let's hope the next year will have as many exciting Matrix projects as this one had!

PS: If you are wondering what the future may bring or what happened last year, don't forget to read The Mega Matrix Holiday Special 2021!

Heisenbridge roundup!

Heisenbridge is a bouncer-style Matrix IRC bridge.

Release v1.8.0 v1.8.1 v1.8.2 v1.9.0 🥳

Finally there's network level spaces support with a new SPACE command. This creates a new bridge controlled space for the network and automatically manages rooms in and out. There's an issue/feature with Element that all rooms that have been converted to DMs with /converttodm will appear in all bridge spaces. The workaround is to convert them back to regular rooms.

CertFP SASL has been updated to do SASL external flow by default. If you are upgrading and have used CertFP with OFTC you need to run SASL --mechanism=none for it to connect again.

Abandoned networks where the user has left all rooms including the network room will now automatically disconnect and cleanup. This is more in line what people would expect and prevents idle connections from hanging around.

Get your third vaccination from GitHub, PyPI or matrix-docker-ansible-deploy!


Matrix Webhook Receiver

An add-on for the matrix-appservice-webhooks bridge. Webhooks are essentially web interfaces for applications to "push" data to. The bridge can receive messages in a certain format, which is nice if the notifying app can be configured. Often it cannot.

matrix-webhook-receiver has hit 1.1.0!

Notable Fixes

Full Changelog:

Dept of Clients 📱


Desktop client for Matrix using Qt and C++17.

Nico shares

Nheko now is a lot more efficient. We now use one Threadpool instead of 3, got rid of more than 60% of the allocations when scrolling through messages, layout half as much content when scrolling, blurhashes decode in 10% of the time and jdenticons allocate ~10% as much temporary buffers. We also deleted around 1000 lines of unused code.

Additionally edits now replace existing notifications, tastytea added a manpage and fixed blurry or incorrectly sized custom emoji, you can now send custom emotes via the inline completer using ~ and completers now show a scrollable list with more Elements than before. Advanced users can also now opt into an insecure client side secrets storage via a hidden setting.

Matrix Wrench

Matrix Wrench is a web client to tweak Matrix rooms.

ChristianP shares

Matrix Wrench is a web client to tweak Matrix rooms. After formerly calling it Matrix Navigator or Matrix Screwdriver, I finally settled on the name Matrix Wrench. ¯\_(ツ)_/¯
Version v0.2.0 comes with a Network Log which displays curl equivalents for all network requests. It also allows to easily add and remove room aliases.


Matrix powered stream overlay for OBS, to integrate live chat in your favorite (selfhosted) streaming setups.

f0x reports

f0x tells us

there's a pink theme and irc styling for matrix-streamchat now

Dept of SDKs and Frameworks 🧰


TypeScript/JavaScript SDK for Matrix bots.

TravisR contributes

matrix-bot-sdk has had a v0.6.0-beta.3 release with beta support for crypto! It even includes documentation!

The crypto is considered beta quality at the moment: good enough to use for somewhat unimportant bots, but not fully recommended for production just yet. With that being said, I'm interested in bugs you run into - please use the issue tracker if you run into crypto not working.

Tutorials for the crypto setup are at

Note for appservice support to work then you'll need a Synapse with these PRs enabled (may require manual merge too):

For non-linux platforms, the rust-sdk will try to build itself which means you might need a working Rust stack. The Rust SDK repo itself has more information:

Bots and appservices don't automatically support encryption, but adding encryption _should_ be easy. The Rust SDK dependency is required in either case, sorry.

Dept of Guides 🧭

Join Matrix!

A beginner-friendly guide to Matrix.

Austin Huang shares

A new Matrix guide has come into town:

In the hopes to expand Matrix's reach to the non-technical population, this guide is intended to give quick directions on how to use Matrix, as well as clear comparison between Matrix and other dominant platforms.
