Getting started/Installation
v5.14.0

Installation#

How to install MQTT.fx and what it needs to run.

System requirements#

  • A desktop operating system: macOS, Windows, or Linux.
  • No separate Java installation is required for end users — the installers bundle a Java runtime.

Download and install#

Download the installer for your platform from https://www.softblade.de and run it. Installers are produced with install4j and are code-signed / notarized.

Installers are available for:

PlatformFormat
WindowsWindows installer
macOSmacOS application package
LinuxRPM and DEB packages (plus a generic Unix installer)

First launch#

On first run, MQTT.fx:

  • Creates its working directory (MQTT-FX) under your user data folder, including the scripts and addons folders and the configuration file. See the Appendix for exact paths.
  • If no configuration is found, treats it as a first run and sets up a default configuration.
  • Shows the licensing dialog. To evaluate without a license, start a Demo Session or request the free trial — see License and trial.

Updating#

MQTT.fx can check for updates at startup; you can turn this on or off with Check for Updates on application start in Settings, and check manually via the menu (Check for Updates).
