Matrix Community Summit 2026 / Call For Your Participation

Yan ‘t’ Minagawa announces

May 21–25, 2026 (Pentecost) c-base Berlin

website | space | general | orga | tickets | schedule

The Matrix Community Summit 2026 is aimed at developers, maintainers, contributors, designers, product managers who work on Matrix-based projects - or who want to experiment with them.

The summit runs for five full days at c-base, enough time to move beyond introductions and engage in substantive work. The focus is on code, product design, architecture, integrations, and honest, constructive peer feedback.

The Matrix Community Summit is a place for everyone who likes working on real problems, and who understands collaborative development as the core of a vibrant ecosystem.

Motto: Beyond Chat

Matrix started as a messaging protocol, but the ecosystem has long grown beyond chat.

At the Matrix Community Summit we explore Matrix as a general real-time collaboration layer: applications, widgets, bots, IoT, shared tools, integrations, experiments, and new kinds of decentralized software.

The motto is intentionally not exclusive. Work on messaging itself, including clients, servers, bridges, federation, security, moderation, and protocol development, remains equally important.

“Beyond Chat” simply invites people to explore what else Matrix can become.

If you like to propose a session please use our session scheduler or drop a note in our hedgedoc. We have a great venue in the heart of Berlin and can be quite flexible but at the same time we want to offer you a schedule. There is some skeleton for formats:

---

Morning

Project presentations in the form of lightning talks, focussing on:

• intention
• concept
• technical overview

Rather than marketing, talks should present:

• the problem statement
• architecture
• current status
• open questions
• specific challenges

These talks can serve as entry points for the project labs.

---

Daytime

Open collaborative workspaces (Project Labs) centered around a specific project or topic. Here participants discuss, test, deconstruct, integrate, and build upon ideas together.

Participants can:

• test projects against their own use cases
• challenge architectural and design decisions
• develop their own features
• collaboratively refine prototypes
• identify or directly resolve issues
• give or receive structured feedback

---

Evening – Hack & Tell

In the evening, everyone reunites for short demos of what was created, refactored, validated, or discarded in the labs.

A chance to share results, lessons learned, and new ideas.

---

Afterwards – Music, Meet & Mingle

Relax and socialize. We will have on saturday a special session on open hardware hack and tell. If you want play some music or present your artwork, just propose a session or contact yan.

---

Submit Your Project

If you want to give a Lightning Talk, a Project Lab or something else, please submit your session idea in Openki.

This helps us to group related topics, coordinate labs and ensure the right people meet each other.

Some slots will remain reserved for spontaneous submissions during the summit.

---

Join the Pre-Meetup Video Calls

To help shape the summit together, we host weekly open pre-meetups.

These calls are for:

• discussing project ideas
• coordinating labs
• meeting other participants
• refining proposals

Every Saturday 18:00 (6pm) CET Starting tomorrow online.

Everyone interested in participating is welcome.

---

Get Your Ticket

If you plan to attend MCS26, please get your ticket early.

Early registrations help us organize:

• space
• infrastructure
• workshops
• catering

With sufficient industry sponsorship (see sponsor tickets) we plan to provide:

• a daily vegan/vegetarian buffet
• a beverage allowance

So the focus can remain on what matters:

exchange, development, and community.

Dept of Servers 🏢

Zendrite

A (new) Matrix Home Server (forked from Dendrite, Go-based).

pat-s reports

Hey community,

As the development around Dendrite has stalled during the last year, a new fork has been created named Zendrite (community choice) which has seen substantial bugfixes and other feature contributions. It provides native Sliding Sync support and runs on the most recent Golang libraries. As a notable goodie on top, it also provides support for ALTCHA, an alternative to Google’s reCaptcha. The effort has been loosely coordinated and discussed within the remaining Dendrite community and all maintainers and member there are aware of the new project. Matthew’s AI prompting skills have come up with the great new icon representing the project.

The docs have been revamped and are now powered by Astro Starlight. The source repo pat-s/zendrite lives on CodeFloe, a Forgejo-based Forge which is hosted in the EU and running on donations.

The migration from Dendrite is seamless and you should see a substantial performance improvement paired with lower memory usage. For further discussions, please join #dendrite-dev:matrix.org and/or open issues in the source repo.

Hammerhead

nex (it/she) 🏳️‍⚧️ announces

Given it’s nearing “completion”, I’ve decided to change course with Hammerhead’s development and instead focus on the client-to-server (and related) APIs, in turn dropping the entire federation component. This has allowed me to drastically reduce the API surface I need to take into consideration when designing new endpoints, massively reducing code complexity, and overall made development significantly easier. Ultimately, Hammerhead can now be used pretty reliably between multiple users on the same deployment, with many clients working with minimal friction.

There’s still no support for E2EE, but device cross-signing is next on my list, alongside typing indicators and read receipts. Account data was the most recent addition, which I’m pretty sure just leaves the E2EE endpoints and a few more miscellaneous endpoints like context and room summaries left to implement. Then I can return to focusing on re-implementing the federation components.

If you don’t know what Hammerhead is, it’s a new small homeserver implementation written in Golang using mautrix-go. There is now documentation at https://timedout.codeberg.page/hammerhead, and if you’re interested in following developments, you can star the repository at https://codeberg.org/timedout/hammerhead, and join the devroom at #hammerhead:nexy7574.co.uk. <3.

Dept of Clients 📱

Element X iOS (website)

A total rewrite of Element iOS using the Matrix Rust SDK underneath and targeting devices running iOS 17+.

Mauro reports

• This week we released on the store 26.03.2, while also creating the RC for 26.03.3
• Redesigned the whole sharing location flow.
• Started implementing Live Location Sharing.
• Migrated our whole CI codebase from fastlane to pure Swift tools.
• More progress was made in implementing an internal migration system between Element Classic and Element X.

Element X Android (website)

Android Matrix messenger application using the Matrix Rust SDK and Jetpack Compose.

Benoit reports

• The release 26.03.3 is making its way to the stores. The content of the release can be found here: https://github.com/element-hq/element-x-android/releases/tag/v26.03.3
• We’re working on the location sharing at the moment. We’re doing some preparatory work to let Element X finally support the live location sharing: integration of the Maplibre Compose library, and iteration on the current design.
• Also working to improve the speed of the notifications, and to make them more reliable.
• And, as a regular basis, we are fixing bugs and polishing the application.

Cinny (website)

A Matrix client focusing primarily on simple, elegant and secure interface.

ajbura reports

This release introduces voice and video rooms. The feature builds on the open-sourced Element Call library, which makes it possible to integrate VoIP functionality directly into Cinny. With this addition, users can create voice or video rooms directly from the client, making real-time conversations much easier within Matrix spaces.

Alongside the new functionality, the release also includes several bug fixes. These address an issue with incorrect matrix.to event link generation, ensure that recently used emojis persist correctly, and fix a crash caused by malformed location URIs.

For the full details, check out the GitHub release page. As always, we’re grateful for the community’s feedback and contributions. For help or questions, please drop a message in #cinny:matrix.org.

Sable & Wally

Joop Kiefte 🟙 (LaPingvino) reports

Thinks have never looked better for Cinny, with Cinny itself now having voice calls upstreamed, and the forks Sable and Wally iterating on what they do best. Wally’s most important niche turns out to be the accessibility support. I would like to call out to the rest of the ecosystem to give proper accessibility more attention, and we’ll be happy to help out to make that happen!

The Wally fork in the meantime has added favorites, drag and drop and other fixes for the issue tracker (that you can use as a widget in any other client that supports widgets, as mentioned in the last update) and steady bugfixes for e.g. DM calling. There is now also experimental support for per message profiles, with a simple interface that should help out most people moving over from Discord with e.g. PluralKit needs. And as I have a lot of rooms that include a lot of active rooms in big spaces (yay Whatsapp Bridge!), I keep iterating on making handling unread chats easier.

While I mostly experiment on my own, the Sable community on the other hand has a very active developer community working out their ideal Cinny experience, so I would love to shout out to their amazing community and recommend you to give that a try first!

Also, if you start using the issue tracker, let me know! I think it can be the start of amazing collaborative projects over Matrix, so I would love to know any communities that give this a try!

Dept of SDKs and Frameworks 🧰

Trixnity (website)

Multiplatform Kotlin SDK for developing Clients, Bots, Appservices and Servers.

Benedict announces

It has been busy weeks for Trixnity! We shipped several updates and are happy to announce that the latest release with Trixnity 5.2.0. This release focuses on performance, developer experience, and polishing things up with a number of fixes.

WebAssembly support

Trixnity now supports WebAssembly (Wasm) as a Kotlin target! This means running Trixnity in the browser just got significantly faster. You may see at least an improved by 2–3× compared to Kotlin/JS.

To make this possible, we also replaced our internally used IndexedDB implementation entirely.

Automatic filter updates

Trixnity supports custom Matrix event types in addition to the standard ones. These events are automatically added to the sync and messages filters so clients receive them without additional configuration. However, there was one annoying issue: when a new event type was added, the existing filter would not update, meaning the client would never receive that event.

This has been fixed now, and Trixnity detects when registered events changed and automatically creates a new filter including the new event types. So your client will always receive the events it supports, without manual intervention.

Bugfixes

We also fixed several bugs. Some of them were introduced with the Trixnity 5 release. A few long-standing bugs that had been lurking around for a while were also fixed.

Trixnity is now used quite widely, but interestingly very few bugs are reported. That makes us slightly suspicious… So if you run into any issues, please let us know! Your reports help make the ecosystem better for everyone.

Matrix Helm Charts

cyclikal reports

tl;dr 10 new bridges and a new Installation Guide! Visit cyclikal94/matrix-helm-charts to find helm charts to quickly deploy ntfy, matrix-appservice-irc and mautrix-* bridges.

Matrix Helm Charts is a collection of… well… Helm Charts for Matrix! Easy to use charts designed to be deployed into Kubernetes to make setting up Bridges, Integrations and other related Matrix Ecosystem things simple.

A brand new room, #matrix-helm:matrix.org has been created to discuss / get support!

What’s new!

Previously ntfy an alternative push notification provider for Android; matrix-appservice-irc an IRC bridge; and the two Python-based mautrix bridges, telegram and googlechat; had been implemented.

This time, work on the Go-based mautrix bridges has been completed, with all 10 updated bridges now having accompanying helm charts!

• These all use a shared base chart, so when new Go bridges appear / changes occur, updates will be simple!
• Double puppetting is enabled by default and uses a shared App Service registration across all charts using the same base chart version.
• Let the charts automatically setup required postgres in namespace, or point them at your own.

Somehow theres been 300+ downloads of the mautrix-whatsapp chart already, with a smattering of love for the others, awesome that people are trying these out / hopefully finding useful! 😁

I plan to work through the matrix.org Ecosystem page for ideas on new charts to add, but suggestions very welcome!

Want to try yourself?

Deploying is as easy as:

1. Downloading the config values.yaml and configuring it to your setup:

   export CHART=mautrix-whatsapp
   curl -L "https://raw.githubusercontent.com/cyclikal94/matrix-helm-charts/main/charts/${CHART}/values.matrix.example.yaml" -o "${CHART}-values.yaml"

2. Installing the chart:

   helm upgrade --install "${CHART}" "oci://ghcr.io/cyclikal94/matrix-helm-charts/${CHART}" \
     --namespace "${CHART}" \
     --create-namespace \
     --values "./${CHART}-values.yaml"

3. For App Service bridges (basically everything except ntfy) give Synapse the App Service Registration file - if you’re using ESS Community it’s just:

   synapse:
     appservices:
       - configMap: mautrix-whatsapp-registration
         configMapKey: appservice-registration-whatsapp.yaml

For more info, I’ve created an Installation guide!
