Making Custom Profiles in Matrix More Useful

For most of the history of Matrix, users have only been able to attach two data points to their profiles: display names and avatar URLs. This changed in August 2025 when Matrix v1.16 included support for Custom Profile Fields (specified by [MSC4133](https://github.com/matrix-org/matrix-spec-proposals/pull/4133)). But while clients could now set and get arbitrary fields, there was no mechanism for getting updates to changes in these fields. That made it unworkable to display fields in timelines or any other "live" UI elements. Profile elements could only really be shown if you specifically clicked on a user. That changed this year when Element began to work on a feature designed to communicate "statuses". They desired the ability to communicate "I'm in a meeting" or "I'm on holiday" without needing to change your display name (and polluting every other room you're in with membership updates). This short talk from Andrew and Aaron at Element details the history, UX design, controversies and technical scalability constraints of designing a live-updating system for profile fields across Matrix.

Implementing Security Labels in Matrix

In defence, government and regulated industry, "who is allowed to see this" isn't a matter of room membership - it's a label against the message itself. Users hold clearances, information carries a classification, and the system should guarantee the two are checked against each other. That expectation is a large part of why many of these organisations are still on older platforms, i.e. XMPP. - What security classifications are, why they're used and who uses them. - What are Security Policy Information Files (SPIF) and how are they used to express security classifications. - A brief look at the proto-MSC written that guided this implementation - A focused look at the work we did in Element Web to support message labels. - How we got synapse to enforce these policies, including talking to an authorisation service. - A live demo that shows all the pieces working together. **Who this is for**: anyone building Matrix for a regulated or classified environment, plus spec and client developers curious about how we approached implementing labelling in Matrix generally.

Disappearing the Protocol: Integrating Matrix into a Multi-App Platform

This talk provides an architectural study of embedding Matrix seamlessly inside a larger multi-app platform. Bypassing basic integration concepts, the focus shifts directly to the specific Matrix components deployed and the automation built to prevent protocol semantics from leaking to the end-user. **Architectural Deep Dive:** * **Identity Automation via ToM (Twake-on-Matrix):** A look at a Matrix Identity Server, with some modifications integrating company-wide directories and extended profiles as well as fully automated user account lifecycle, keeping Matrix profile management entirely invisible to the user. * **State & ACL Sync via Twake Bridge:** Determining system authority remains the hardest part of integration. An application service automates synchronization between a platform's native HRIS-style user/group ACLs and Matrix's room/power-level state, ensuring overarching platform rules dictate Matrix room behavior instantly and automatically. * **The Edge of Automation:** An open design discussion on where the illusion breaks. Should Matrix room attachments share quota semantics with a platform's broader file storage ecosystem? A critical look at the unsolved boundaries of shared storage, media ownership, and sync direction.

A concise overview of the current state: the dual form factor (Matrix widget for Element Web and a standalone Matrix client), the open-source release under AGPL-3.0, the infinite canvas, CRDT-based real-time collaboration via MatrixRTC, and the product's place within the openDesk suite. This sets the stage for an audience that may know NeoBoard from previous conferences but wants to understand where the product is in mid-2026. The deployment at "DAP Digitaler Arbeitsplatz für Lehrer in Baden-Württemberg" for 86K users will be NeoBoard's largest public-sector deployment, and sits within the broader openDesk ecosystem already serving tens of thousands of users across German public institutions.

Robrix: a pure Rust multi-platform Matrix client, and a peek at its future

[Robrix](https://github.com/project-robius/robrix) began as a flagship application test case and driver for the cross-platform development of [Makepad](https://github.com/makepad/makepad) and [Robius](https://github.com/project-robius), but has since become a real project in its own right. While it's not yet 100% complete, we've achieved near feature parity with other big Matrix clients, and that gap is closing every week. ### First half: current state + demo In the first half of this talk, we'll give an overview and live demo of Robrix's current design and core Matrix functionality. Beyond the goals of flexibility and productivity for users who want it, we also prioritize consistency: all UI experiences and features are available on **every device** and **every platform** – we don't restrict features just because you're on your phone. While Robrix itself is platform-independent (aka, easy to contribute to! 😊), it runs natively on iOS, Android, macOS, Windows, and Linux (X11 & Wayland). Web/WASM and HarmonyOS/OpenHarmony are mostly supported but need a bit of TLC. Importantly, since we control the entire stack, we can achieve deep integration with underlying OS services and platform features, all without a heavyweight framework or web engine like Electron. Integration layers can even be customized, allowing us to improve upon known limitations of other frameworks like Flutter. Publishing Robrix to app stores has also validated our earliest objective: one can successfully distribute cross-platform Rust apps through platform-native channels despite bypassing those platforms' native UI frameworks and build systems. ### Second half: future & in-progress work In the second half of this talk, we'll explore some potential future directions. One example is leveraging Matrix as the medium for coordinating and managing multi-agent workflows, which are becoming increasingly popular. We envision an agent being able to generate or download dynamic "mini-apps" written in *Splash*, Makepad 2.0's UI scripting language, that can be safely interpreted in a streaming manner within a resource-isolated sandbox. This would enable an agent to create things like a **custom interactive status dashboard** _directly within a room_, which would be accessible on any device, even restricted systems like iOS. We could even inject custom dependencies, such as the Matrix Widget API, into a custom Splash mini-app to enable it to access room info, user context, and timelines with the existing capability-based permissions model. This combination of Robrix's rich UI and the Matrix Widget API could elevate Matrix to become the ideal choice for agent coordination, surpassing Telegram, the de facto choice for chat-room-like coordination between agents. Beyond that, we'd also like to experiment with integrating *on-device* models for simpler, more practical utility features, e.g., summarizing a few weeks of missed messages in an E2EE room (preserving privacy) or answering user questions based on room history.

Digital Sovereignty Is No Longer a Buzzword — It's Procurement Policy

The presentation argues that digital sovereignty in healthcare IT has shifted from an abstract ideal to a concrete procurement requirement, using the Matrix protocol as the case study for sovereign communication. It builds the case in three acts: 1. The problem — clinical staff still default to WhatsApp despite sovereignty rhetoric; sovereignty means independence, not isolation. 2. The evidence maps the three layers / four platforms of the sovereign-communication landscape, shows 20+ European governments have already mandated it, identifies the four drivers (regulatory, security, cost, geopolitical) turning it into an obligation, and shows what sovereignty requirements look like inside an actual tender. 3. The complication and the ask — reach still lag adoption, an August 2026 inflection point in uptake, reasons adoption remains slow, the risk that no single vendor controls the standard, and closes with four concrete asks for stakeholders before the policy window closes.

This talk is intended for Matrix contributors, homeserver administrators, community organizers, client developers and anyone interested in the governance and long-term sustainability of the Matrix ecosystem but also bigger organizations, that want to learn about the real benefits of federation and consider opening up their instance. _In case you don't know about the Working Group, you can find all our information [here](https://github.com/cleverer/matrix-wg-promote-alternative-homeservers) or ask in our [matrix room](https://matrix.to/#/%23homeserver-decentralisation:matrix.org)._ PUBLIC CONFIRMED Talk https://cfp.2026.matrix.org/matrix-conference-2026/talk/HKSYET/ Sofya Nicolas Da Mutten PUBLISH ZAMKVT@@cfp.2026.matrix.org -ZAMKVT Widgets Working Group en en 20261022T164500 20261022T171000 002500

Widgets Working Group

Matrix Widgets have long been an underutilised part of the ecosystem — powerful in theory, but held back by fragmented definitions, limited discoverability, and inconsistent client support. At Matrix Summit 2026, a group of community members came together to change that. The newly founded Matrix Widgets Working Group of the Matrix Foundation is taking on the challenge: establishing a shared taxonomy for what a "Widget" actually is, mapping user needs and use cases, and laying the groundwork for a thriving app ecosystem — including a widget catalogue or App Store that makes widgets accessible and trustworthy for all Matrix clients and users. In this talk, we will share: - Why we founded the WG and what problem we are solving - Our working definition of Matrix Widgets and how it differs from what exists today - The key topics the WG is working on: Discovery & Distribution, Developer Experience, Mobile Support, and more Current results, open questions, and how you can get involved Whether you are a client developer, a widget builder, or simply curious about the future of apps in Matrix — this talk is for you.

NI2CE network effects in a voluntary adoption paradigm

NI2CE is a messenger solution that we deployed for NATO users to provide a safer and more private alternative for the widespread use of Whatsapp and Signal. The use of NI2CE is optional as users need to install it on a personal device for mobile use. I had hoped that reaching a critical mass of users would increase adoption and lead to a quick growth of users. This has not materialized unfortunately. In this talk, I would like to show how we tried to convince users to migrate and would like to get the points of view of other organisations that might deal with this.

Common challenges for organizations when deploying [matrix]

Among others things, we will take a (somewhat quick) look at: - User provisioning: - why not just OIDC? pre-populating users from user identity stores, chat integration into different systems (moodle, addressbook) - matrixID: human readable or not? (approaches to namechanges and account lifecycles, the state of portable identities) - mapping of the organizational structures into matrix: spaces, rooms, using existing providers like LDAP and its pitfalls, room/member sync/provisioning etc - Law: GDPR and misconceptions, federation, data retention, E2EE settings and auditability - Administration tools (ketesa, synadm) and challenges (MAS migration, DB, media-store, reports) - Moderation: community tools and policy server (draupnir), admin actions (reporting, suspend, redact, shadow/ban, block, delete, clean up spam), precautions (media handling, draupnir+antispam module, room discovery) - Viable matrix clients - potentially useful plugins/extensions: - collaborative whiteboard (Neoboard), meetings organizer (NeoDateFix) - bots, integrations, services: - bots: AI/LLM bots (baibot), auto-translations, helpdesk, etc - webhooking (hookshot): alerts, jira-tickets, git notifications, feeds - bridges (mautrix) - Videocalls: livekit/BBB, Jitsi, selfhosting the SFU - Challenges for users: E2EE, room permissions (deopping, admin/mods), clients (+client configs), usability/accessibility - Typical infrastructure challenges: storage, monitoring, logging, hosting, deploying (k8s, ansible, ESS), scaling, typical performance bottlenecks - Some of our custom made solutions: - custom search injection and ranking (maiden) - problems with the matrix vanilla spec (deopping of chatrooms, invite permissions) - fluffychat client for schools at RLP (addressbook, tools for teachers) - custom-tooling for RLP (IDM-proxy, dashboard) PUBLIC CONFIRMED Talk https://cfp.2026.matrix.org/matrix-conference-2026/talk/37GLHX/ Katherine Jan Krammer (Janonym) Philipp Monz PUBLISH KS3A8F@@cfp.2026.matrix.org -KS3A8F Starting a Sovereign Chat Project in the Dutch Government: Early Lessons en en 20261022T161500 20261022T164000 002500

TI-Messenger goes Europe: Austrian healthcare adopts matrix protocol

On January 1, 2025, Austria officially discontinued the use of fax machines for exchanging patient data. While a necessary digital milestone, this abrupt shift initially led to a highly fragmented landscape of disconnected replacement solutions. Recognizing the looming interoperability crisis as early as 2024, state and federal institutions began searching for a unified, scalable alternative. Drawing inspiration from Germany, the TI Messenger was quickly identified as a highly promising blueprint for a nationwide fix. This catalyzed a wave of regional innovation. In Salzburg, an informal pilot successfully connected the state hospital holding company (Salzburger Landeskliniken) with regional doctors' offices. This was achieved through a collaboration between industry partners Famedly and x-tention, alongside "Medspeak," a grassroots Matrix server initiative hosted by two local physicians. Simultaneously, Austria's national regulatory authority (Elga GmbH) began drafting a standardized specification for adopting the Matrix protocol in healthcare communication nationwide. Famedly was awarded the contract to consult on the foundational version of this specification. Currently, the State of Vienna is conducting a major pilot to validate this standard, working closely with industry partners such as Famedly, x-tention, and Cloudflight. This talk explores the evolution of Austria's transition toward a unified, Matrix-based healthcare communication infrastructure, offering unique insights and lessons learned from Famedly’s perspective as a driving industry partner.

Side Effects Include: Data Breaches, GDPR Fines, and a Group Chat With 47 Nurses

This is a talk about three people. Amira is a home care nurse. Her "ward" is eleven living rooms and a car. Nobody from IT has ever been in any of them. Mateo is a hospital nurse on night shift — issued a phone, a pager, and a login that expires every 8 hours. Dr. Chen is a doctor. Always reachable, never has time. Three people, three employers, three different IT policies. Same behaviour: they all use WhatsApp. Not because they don't know better. Because the secure alternative is slower, harder, and breaks the workflow that actually keeps patients safe. This talk walks through the data. What the research says about clinician use of consumer messaging apps. What regulators have actually done about it (€1.2B in GDPR fines last year, healthcare enforcement up 26%). And why dedicated solutions built on open standards like Matrix — including the CGM Messenger and CGM TI-Messenger shipping into European healthcare — are still sitting at ~20% adoption. Every country, same pattern. The fortress works. The side door works better. And patients got better care through the side door. The talk closes on AI. Ambient documentation, intelligent message routing, AI-assisted triage. The first time convenience and compliance may be pointing in the same direction. But AI processing patient data inside messaging platforms also raises urgent new questions about data sovereignty and consent. We can't skip the conversation just because the technology is finally convenient. For Matrix developers shipping healthcare products, healthcare IT professionals, and policy makers who want to know what it will genuinely take to move healthcare off WhatsApp — and what role open protocols play in getting there.

Matrix Wrench - an admin tool for operators and community managers

In my time at the Matrix.org bridges team, I had worked on a few of the largest bridges operated at the time. Routine tasks included supporting the community leaders, e.g. when room admins had made mistakes or became inactive. With the administrator role of the bridge bot, we we're able to modify the room state, revoke rights and promote new community leaders to administrators. What started as a lot of manual, error-prone work in the terminal with curl became a web app written for the job. It allowed us as operators and community managers to tweak the rooms easier and faster. Wrong permissions? View them. Fix them. Wrong room visibility? Easy fix. Lots of unwanted accounts? Kick them at once. Migrate a community to a new room? Copy the state and members you want. Matrix Wrench is closely built around the Matrix API endpoint. Most buttons only fire one network request. Many actions have simple forms, so you don't need to look up the Matrix Spec in a hurry. And if you want to replicate any of the actions in Matrix Wrench, e.g. for an automated script, you can have a look at its Network Manager which shows a curl command for all performed requests.

Speedrun Client with the Matrix Rust SDK

The Matrix Rust SDK is one of the most complete SDK in the world. It's becoming really mature: more and more clients are relying on it due to its great features, stability, and performance. Maybe you want to give it a try for your own great client? To illustrate our point, we demonstrate how to develop a Matrix CLI client from scratch with the Rust SDK, step by step, up to having a fully functional client, with a room list, a timeline, the ability to send and to receive messages, along with full end-to-end encryption support. We will use the following components: `SyncService`, `RoomListService`, `Timeline`, `SendQueue`, `EventCache` and so on.

When the Bridge Looks Like an Attacker: Building a Focus App on Matrix Instagram Bridges

The problem: why a focus app needs to keep messaging at all, and why "just open Instagram" defeats the purpose. Why Matrix: choosing puppeting bridges over alternatives, and how the app sits on top of mautrix-instagram / mautrix-meta. What broke: the collision with Meta's anti-abuse systems: unfamiliar-login flags, ban warnings reaching real users, read receipts, proxy and session-handling changes, and reliability under active pushback, scaling issues. trust and privacy tradeoffs of routing user sessions through a bridge, and what shipping to thousands of non-technical users revealed about whether consumer-facing bridges are durable.

Making Matrix Feel Like WhatsApp Without Centralizing It

Matrix gives us federation, interoperability, end-to-end encryption, and the possibility of communication networks that are not controlled by a single vendor. But the average user does not want to think about homeservers, server names, Matrix IDs, login methods, federation topology, or trust boundaries. In many countries, messaging products such as WhatsApp became dominant partly because onboarding is extremely simple: enter a phone number, receive a code, and start talking. Gua explores whether a Matrix-based messenger can offer that kind of simplicity without giving up the federated architecture underneath. The project is a distribution and product experiment built around the Matrix ecosystem. It forks Element clients for iOS, Android, and Web, forks Synapse and Matrix Authentication Service where needed, and adds Gua-specific Java/Spring services such as identity-service and gua-resolver. It also includes gua-idp-web, a web frontend for the identity provider login flow. The design makes several deliberate UX and architecture choices: - users see usernames, not full Matrix IDs or homeserver names; - clients do not ask users to choose a homeserver; - the public demo uses phone-number OTP onboarding; - returning users can use a 6-digit account PIN as two-step verification; - passkeys and other identity providers can be added through the OIDC/MAS pattern; - the resolver decides where a user should log in or register inside the Gua federation; - trusted homeservers are admitted and verified through a resolver-controlled roster. The talk will walk through how Gua Identity Service acts as an OIDC provider for MAS, how the Gua MAS fork reduces login friction for first-party clients, how gua-idp-web drives the phone -> OTP -> PIN/profile flow, and how gua-resolver ties the model together by resolving identities to homeservers and maintaining trust in the federation. It will also discuss future potential directions: institutional deployments, login through SSO providers, and eventually bridging the user experience beyond the Gua-controlled federation toward the broader Matrix federation or other controlled Matrix federations such as Tchap. Gua is an early-stage architecture and product-design case study about making Matrix federation usable for people who would otherwise never adopt a federated messenger.
