Our licenses count by sensors. We define one sensor as one aspect that you monitor on a device.

There are four different PRTG flavors available.

Freeware Edition

The Freeware Edition is a good solution to get started with PRTG or for private use:

  • Is for free for personal and commercial use.
  • Can monitor up to 100 sensors.
  • Supports all available sensor types.
  • Shortest available monitoring interval is one second (not officially supported; a minimum interval of 10 seconds is recommended).

Note: If you want to use the Freeware Edition, please first install the Trial Edition and get a free trial key. After the trial period has ended, your Trial Edition will automatically revert into a Freeware Edition.

Trial Edition

The Trial Edition is intended for evaluation purposes for customers who are interested in purchasing commercial licenses:

  • Can monitor an unlimited number of sensors.
  • Supports all available sensor types.
  • Shortest available monitoring interval is one second (not officially supported; a minimum interval of 10 seconds is recommended).
  • Temporary license key must be requested from Paessler's website.
  • Trial period limited to 30 days (automatically reverts to Freeware Edition afterwards).
  • With each license one single failover cluster setup, consisting of two nodes, is included. Cluster installations with two and three failover nodes will require one additional trial license key; a cluster installation with four failover nodes will require two additional trial license keys.

After the trial period has ended, a Trial Edition will revert into a Freeware Edition, allowing you to monitor up to 100 sensors for free.

Commercial Editions

There are several licenses of PRTG Network Monitor available to suit the demands of smaller as well as larger customers and organizations:

  • Can monitor a maximum number of sensors.
  • Supports all available sensor types.
  • Shortest available monitoring interval is one second (not officially supported; a minimum interval of 10 seconds is recommended).
  • With each license one single failover cluster setup, consisting of two nodes, is included. Cluster installations with two and three failover nodes will require one additional license of the same size. A cluster installation with four failover nodes will require two additional licenses of the same size.
