The First XMPP Messenger with Extensible REST API, AI Support, MQTT & Advanced Security Features
Built for ultimate privacy with OMEMO 1 + 2, integrated OpenPGP Key Manager, integrated Tor & Obfs4proxy and full local database encryption. WebRTC Audio/Video Calls, decentralized MUJI Group Video Calls (hardware accelerated), voice messages, video messages, message retraction and advanced MUC moderation — all in a modern GTK4/libadwaita interface with System Tray support.
Local API Server, Botmother Bot Management and AI Integration (9 providers incl. OpenClaw). MQTT Plugin for IoT sensor data, topic subscriptions, sparkline charts, XMPP bridging, Home Assistant integration, ejabberd & Prosody support, and Node-RED integration. DTMF Support (RFC 4733) with Dialpad UI for XMPP SIP Provider telephony.

Download the latest Windows build from GitHub Releases. Extract the ZIP archive and run dinox.exe.
To build DinoX from source on Windows, see the build instructions: Deutsch | English
The first time you start it up after unpacking may take a little while; just skip the Windows warning. GStreamer and the necessary databases are being set up in the background; on the second start, Windows Defender will run a scan again, which also causes a slight delay, but after that Dinox will start up normally. The same applies if you build it yourself from the package repositories.
Geolocation for locations is not available on Windows.
Download from GitHub Releases
# 1. Install the GNOME runtime (required, one-time setup)
flatpak install flathub org.gnome.Platform//48
# 2. Install DinoX (replace ARCH with x86_64 or aarch64)
flatpak install --user dinox-*-ARCH.flatpak
# 3. Run
flatpak run im.github.rallep71.DinoX-
Download from GitHub Releases
chmod +x DinoX-*.AppImage ./DinoX-*.AppImage

Install via AppMan (rootless)
appman -i dinox
-
Install via AM
am -i dinox
Install on Arch Linux using the AUR dinox package.
Replace with your preferred AUR helper.
paru -S dinoxDinoX uses Meson/Ninja and requires several custom dependencies (SQLCipher with FTS5, webrtc-audio-processing 2.1, libnice 0.1.23, etc.). For complete build instructions including all dependencies, distro-specific notes (Debian/Ubuntu, Fedora, Arch), and the automated build script, see BUILD.md.
DinoX stores your local data (accounts, messages, settings, cached metadata) in an encrypted SQLCipher database.
- You will be prompted for a password on startup.
- If you forget the password, the database cannot be recovered.
- A Panic Wipe action is available via the app menu and the shortcut
Ctrl+Shift+Alt+P.
DinoX 1:1 calling focuses on cross-client interoperability (notably with Conversations (Android) and Monal (iOS)) while keeping the existing media stack:
- Media stack: GStreamer (RTP/rtpbin + WebRTC elements),
libnice(ICE),gnutls(DTLS),libsrtp2(SRTP). - PipeWire Support: DinoX integrates explicitly with PipeWire for modern audio support.
Important: If your system uses PipeWire (common on Fedora, Manjaro, Mint 22+), you must install the GStreamer PipeWire plugin (usually
gstreamer1.0-pipewireorgst-plugin-pipewire). This is a separate package from standard GStreamer plugins! Without it, calls or voice notes will fallback to the legacy sound server (Pulse/ALSA), which may lead to stability issues or incorrect device selection. - Security profile: DTLS-SRTP only (no SDES-SRTP).
- Baseline codecs: Opus (audio) and VP8 (video) for reliable interop.
- Optional audio quality:
webrtc-audio-processingenables AEC/NS/AGC if present.Note: Many distributions ship outdated versions. For best quality (Echo Cancellation), we strongly recommend building version 2.1+ from source. See BUILD.md.
If you are building from source using distro packages, ensure you are on a sufficiently new libnice (recommended: >= 0.1.23). For collecting reproducible call logs, see DEBUG.md.
