DinoX

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.

47 Languages	~85% translated
Dark Mode	System theme or manual toggle

Installation

Windows

Download the latest Windows build from DinoX 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.

Flatpak

Download from DinoX Releases

# 1. Install the GNOME runtime (required, one-time setup)
flatpak install flathub org.gnome.Platform//49

# 2. Install DinoX (replace ARCH with x86_64 or aarch64)
flatpak install --user dinox-*-ARCH.flatpak

# 3. Run
flatpak run im.dinox.dinox

AppImage

• Download from DinoX Releases

  chmod +x DinoX-*.AppImage
  ./DinoX-*.AppImage
  

• Install via AppMan (rootless)

  appman -i dinox
  

• Install via AM

  am -i dinox
  

Build from Source

DinoX uses Meson/Ninja and requires several custom dependencies (SQLCipher with FTS5, webrtc-audio-processing 2.1, libnice 0.1.23, etc.). The current source-build reference is Debian/Ubuntu 24.04 based systems, including Linux Mint 22.x. For complete build instructions and packaging notes, see BUILD.md.

Local data encryption

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.

Audio/Video calling notes

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: On Debian/Ubuntu based systems, install gstreamer1.0-pipewire. Without the GStreamer PipeWire plugin, calls or voice notes may fall back to legacy audio paths, which can cause 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-processing enables AEC/NS/AGC if present.

  Note: Many distributions ship outdated versions. For best quality (Echo Cancellation), use the tested dependency set from scripts/ci-build-deps.sh. 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.
