A quick update on what's changed since my last post. Two beta dropped over the past few weeks. I would like to share this here so that I can possibly find my audience.

[1.2a-beta] — 2026-04-07

Added

Application autostart — the app can now start automatically on system boot, Windows.
Message animations in external groups and channels — animations were missing in external (self-hosted) instances, now consistent across all chat types

Improved

Editing and deleting messages in groups and channels — this was broken or limited in non-external groups/channels, now works properly

Fixed

Favorite icon color display in edit mode
Voice message duration display in send preview

[1.3-beta] — 2026-04-21

Added

Message reactions — react to messages
User blocking — block list and the ability to block individual users
Hide content in notifications — shows "New message" instead of actual content on the lock screen
PIN and biometric prompt when switching accounts — multi-account users now need to authenticate when switching, prevents unauthorized access if someone has physical access to the device
Relog notification — notifies when session token is expiring instead of silently failing
Video download progress — progress indicator when downloading videos from the server

About the project

Fair question. The honest answer is: it depends on what you need. Matrix is a protocol with federation, a large ecosystem, and years of development behind it. If you need federation or interoperability with other services, Matrix is the better choice. ONYX is different in a few ways:

LAN mode — works entirely without internet via UDP broadcast, no server needed

Simpler self-hosting — one binary, runs from the command line, no complicated setup

Native Flutter client — single codebase for Android, iOS, Windows, macOS, Linux

The tradeoff is that ONYX is less mature, still in beta, and doesn't have federation yet (it's on the roadmap). If you're already happy with Matrix, there's probably no reason to switch. If you want something lighter and simpler with a focus on privacy and offline capability, it might be worth trying.

Hold up, how do you find each other without a server? You just keep track of everyone's IP addresses?

Just to clarify — LAN mode is an optional feature, not the only way the app works. By default ONYX works like any other messenger through a central server, with E2EE for private chats (unlike Telegram, where only Secret Chats are E2EE). LAN mode is an additional feature for people on the same local network who want to communicate without any internet or server involved at all — useful for office environments, local events, or situations where internet access isn't available or isn't wanted. So to answer your question: in normal mode, the server handles routing. In LAN mode, UDP broadcast handles discovery automatically — no manual IP tracking needed.

That's neat! Thanks for taking the time clarifying.
