SABnzbd is an Open Source Binary Newsreader written in Python. It can be run as a Windows Service using FireDaemon Pro, which allows you to have the application start automatically at boot prior to login, start multiple instances of the application and more. This HOWTO will show you how to set it up. You can also use Fusion to manage FireDaemon and other Windows services via a web browser.

SABnzbd Setup Under FireDaemon Pro

Download the latest SABnzbd files from here.

By default, SABnzbd installs to C:\Program Files (x86)\SABnzbd. For the purposes of this HOWTO, we will use that directory.

After installation, you will need to start SABnzbd and configure it through its browser-based wizard at


Download and install FireDaemon Pro into the directory of your choice, typically C:\Program Files\FireDaemon.

Next, start the FireDaemon Pro GUI from the desktop shortcut. Click on the "Create a new service definition" button in the toolbar (or type Ctrl+N) and enter the information into the fields as you see below. Adjust the paths to suit your installation. Note the required parameters.

The most important field on the tab is the Parameters. The Parameters define the initial setup of your SABnzbd client. Failure to fill it out means your client will not automatically connect to a specific server and channel.

Here’s the full parameter list you should have:

  • -d Starts the application in daemon mode and does not open a web browser configuration window.

Now click on the Settings tab. If you DON'T want to see SABnzbd running, uncheck the Interact with Desktop check box & select “Hidden” from the “Show Window” dropdown. You must run SABnzbd as the user you installed it as. In the Logon Account field type your username (e.g. Administrator) and then enter the user's password twice in the Password and Confirm fields. You can change the Process Priority to allocate more CPU time to SABnzbd or specify which CPU or core SABnzbd will run on (in the case of multi-processor, hyperthreaded or multi-core CPUs). You must change the "Job Type" to "Global Job", otherwise when SABnzbd is restarted any child processes will not be terminated properly.

Now click on the Lifecycle tab and check "Console application".

Now click on the OK button to install and start SABnzbd!
