quick heads up. Our impressions: #matrix is going strong with public sector entities, and it's where most dynamics happened at the conf.
We are rather focused on private and resilient messaging where servers don't play a big role; as we want #chatmail relays to be dirt cheap to operate, no pro version needed. Our focus is on informal usage, groups, family, friends, affinity or interest groups, whereas matrix is increasingly focusing on corporate/ organizational use cases. YMMV
☁️The recent AWS outage showed how fragile “cloud-based security” can be.
When one datacenter faltered, global communication tools — including Signal — went dark 🌑
🕸️Matrix-based messaging systems kept running because they don’t rely on a single provider.
Resilience = decentralization
Let's invest in open, federated platforms.

Hey, did you know that Movim allows you to link your #Discord, #Telegram, #WhatsApp and #Matrix accounts to your main XMPP one and chat with all your contacts in one integrated platform? 🤩
We are working hard with @nicoco to ensure a perfect integration with the Slidge gateways project slidge.im/ 🥸🤝🥸
Message synchronization, reactions, stickers, GIFs, chatrooms, invitations, file transfer... you can now find all those exciting features fully working across all your linked accounts in Movim ✨.
Now you can move to #XMPP while staying in contact with all your friends. 👌
Try it out on mov.im/ or by deploying your own instance 😸!
Venue clean, all remaining items packed. Good-bye Kaleidoscoop, thanks a lot to all volunteers, the @matrix foundation, our sponsors, our speakers and my friends @thibaultamartin and @HarHarLinks for rocking the #MatrixConf2025.
Se y'all on #39c3 !
Important message from my talk!
Exclude Insecure Devices is coming!
After April 2026 (or maybe even sooner), if your Matrix device is unverified, you will not be able to talk to someone who is using Element!
Or any other client complying with MSC4153
@TheDailyBurble, happy to help.
Another cool feature of #XMPP are "gateways" that make it relatively easy to connect with other IMs.
e.g.
#Libervia to #ActivityPub and #email (CC @Goffi )
nlnet.nl/project/Libervia
libervia.org
#Slidge to all sorts of other IM like #Matrix, #Mattermost, #Steam, #Discord, #Whatsapp, FB … (CC @nicoco )
slidge.im — Gateways from XMPP to Other Networks
Slidge is a chat gateway library for XMPP built in Python, and a set of gateways for other networks.slidge.im
Not related to the outage, really, this morning I found myself searching for federated IM protocols, ideally end-to-end encrypted. I know we have @matrix but was looking for something more DM-oriented like Signal, but federated.
Looked into XMPP, but E2E encryption relies on add-ons. It seems the closest we have to that is actually #Matrix.

Exhausted, happy and looking forwards for next year's conference.
Time to travel home. Thank you all for attending and making the #MatrixConf2025 possible. It was an honor to organize this conference for you !

We had an amazing after show gathering with the activists from @hackstub after a successful last evening of the #MatrixConf2025. It was an interesting exchange, we learned a lot about your work and it was super pleasant to network with other hackers sharing our vision and values we bear as the ecosystem.
Now time to catch some sleep before rocking the last conference day.
Good night & see you tomorrow !
After fixing some issues, migrating my #matrix media off #matrix-media-repo and onto #synapse was surpisingly straightforward.
I've written a short step-by-step list on what to do and put it here for now:

@fairkom is a silver sponsor of the matrix foundation and will present their experiences deploying SchulchatRLP for half a million pupils, teachers and parents on Sat Oct 18th 10:00. The greatest challenges were syncing users and groups from a central IDM and building a #kubernetes cluster on premises.

Beeindruckend finde ich den lebendigen und vielfältigen Austausch in den #Matrix Räumen von @librechurch@kirche.social auf synod.im
Von Fragen und Ideen zu digital souveränen Tools, die auf dem Marktplatz diskutiert werden bis zu Erfahrungen und Herausforderungen immer kleiner werdender christlicher Gemeinden im Raum Glauben teilen.
I use it on Android alongside with other #Matrix Clients.
So far I remember, the onboarding was good. Generelly it feels fast (after) sync.
The chatlist items, for me, could have a little bit more padding. The gui with the bubble style in the Chats I don't like much.
It's nice to have some settings for gui. The accent color could have more options.
Anyone using #Tammy as a #Matrix messenger client?
What do you think about it? Why do you use it? How much do you use it? On which device type is it installed? What features do you miss?
- Yes. (15%, 3 votes)
- No, but already tried it. (5%, 1 vote)
- No, but heard about it. (15%, 3 votes)
- No, never heard about it. (65%, 13 votes)
I would not underestimate the value of having a go-to home server free of charge for people new to #matrix. In the end, it is the members of the foundation to decide whether they agree with the use of the budget they contribute. Are you also a member?

Regarding the more general accusation on #Matrix being just another VC-backed one-company-product, I'd like to refer to another recent post from the foundation, and only quote from its final paragraph:
> … triggered some defensive reaction with other European players in the market. It is a shame that small European players feel the need to fight one another rather than collaborate via open source software against the bigger non-European and proprietary players.

Dispelling myths and misinformation
Matrix, the open protocol for secure decentralised communicationsRobin Riley (matrix.org)
The Matrix Foundation now has some volunteer working groups, and a formal process for creating new ones;
matrix.org/foundation/working-…
For example, there's a WG for documenting moderation issues; reducing spam, easier handling of trolls, griefers and grifters.
If you're keen to get involved in keeping the Matrix protocol network fully decentralised, surveillance-free, and non-corporate, this could be a good way.
#TIL that Mattermost is now offering its own bridge to Matrix, which depends on a Synapse instance running alongside the MM server;
mattermost.com/marketplace/mat…
This is what RocketChat were doing since about 2022. Although their documentation suggests they are working on full Matrix support inside the RC server itself, due sometime this month;
Woah! Only now did we discover a great blog post from @wq who discusses the progression from hosting a #Matrix , a #Snikket and a #SimpleX server, to now running a #chatmail relay runtimeterror.dev/self-hosted-…
It's an excellent read, with lots of good advise, including having a public "hello" profile and another unpublished chat profile for private chatting. #deltachat apps have pervasive multi-profile support (and multi-device support) so it's pretty easy to establish such a two-profile setup.
Als Chat-Alternativen könnte man vielleicht aus verschiedenen Gründen stärkeren Fokus auf #Matrix legen als auf Signal.
Everyone is now realizing that WhatsApp is evolving towards its latest form (archive.md/L3W74). If you value secure messaging, you may want to check out @signalapp or @matrix (wich is #federated). EPFL also has its own Matrix instance at matrix.epfl.ch (use @element as a client).

The past few days I've been building a small tool for checking how many members of a given Matrix room support which maximum room version. The idea has been sparked by room version 12 being released, so that one can assess the adoption rate for the new room version and make an educated decision on when to upgrade rooms.
You can check it out here:

We released version 0.12.1 of #nheko! This release includes a few security fixes around html escaping into the UI and properly attaching a mark of the web on Windows. I highly recommend you upgrade!
This release also takes the first steps to room version 12 compatibility regarding the upcoming #matrix security release.
You can find the release here: github.com/Nheko-Reborn/nheko/…
Enjoy! :)
